The academic world, at least in the West, has traditionally always been suspicious when it comes to introducing in its quest for knowledge notions of materiality, touch, texture, or “haptics” – in other words what is generally associated with sensory-experience. In the human sciences and the artistic fields the practice of research has always privileged “textual reason” over “sensory texture,” the textual over the textural. Only in the recent past have so-called postmodern theories of all kinds attempted to overcome the hierarchical dichotomy between discursive reason and embodied thought. Unfortunately, this has very often created an unprecedented ragbag of epistemological confusions and identity crises. This essay shall attempt to explain and clarify the epistemological nature of materiality, touch, texture, or “haptics,” and the role it can play in academic research in the artistic fields with particular reference to ideas developed by French philosophers Maurice Merleau-Ponty and Emmanuel Levinas.

A major problem of texture analysis is that textures in the real world are often not uniform due to variations in orientation, scale, or other visual appearance. In this paper, affine texture analysis with texel scale-area histogram is presented. A textural image is decomposed into a set of scale images and each scale image consists of square texels of the same size. The scale-area histogram of texel is used as texture feature for multi-scale texture analysis and dominant texture scale analysis. Measurement of the dominant texel sizes of textural images with different rotation angles and spatial scales indicates that rotational and scaled transformations of textural image result in the motion of translation in scale-area histogram.

Currently, screen content images (SCIs) are widely used in our modern society. However, since SCIs have distinctly different properties compared to natural images, traditional quality assessment methods of natural images cannot precisely evaluate the quality of SCIs. Thus, we propose a blind quality evaluation method for SCIs based on regionalized structural features that are closely relevant to the intrinsic quality of SCIs. Firstly, the features of textual and pictorial regions of SCIs are extracted separately. For textual regions, since they contain noticeable structural information, we propose improved histograms of oriented gradients extracted from multi-order derivatives as structural features. For pictorial regions, since human vision is sensitive to texture information and luminance variation, we adopt texture as the structural feature; meanwhile, luminance is used as the auxiliary feature. The local derivative pattern and the shearlet local binary pattern are used to extract texture in the spatial and shearlet domains, respectively. Secondly, to derive the quality of textual and pictorial regions, two mapping functions are respectively trained from their features to subjective values. Finally, an activity weighting strategy is proposed to combine the quality of textual and pictorial regions. Experimental results show that the proposed method achieves better performance than the state-of-the-art methods.

1 ABSTRACT
The objective of this work was to the evaluate the effect of irrigation and soil texture on the growth of branches and fruits of peach tree cv. Esmeralda. The study was developed in a commercial peach orchard, cv. Esmeralda, in Morro Redondo – Rio Grande do Sul state. Irrigated and non-irrigated plants were evaluated in two textural class (Sandy Loam and Sandy Clay Loam) in a total of four rows of peach. The irrigation management was based on the replacement of the potential crop evapotranspiration. The parameters of growth evaluated were: fruit growth and fruit growth rate, branch growth and branch growth rate. The results led to the conclusion that irrigation increases the diameter of the fruits of the peach crop by 5% in the Sandy Loam textural class and by 18% in the Sandy Clay Loam textural class; irrigation provides an increase in the size of the peach tree branches, especially after fruit harvesting, by 6% in the Sandy Loam textural class and 16% in the Sandy Clay Loam textural class; more clayey soils show the influence of irrigation more pronounced than in soils with higher sand contents as the soil of the present study, increasing fruit and branch growth.
Keywords: Prunus persica (L.), irrigation management, peach orchard.

A calagem interfere na disponibilidade de nutrientes, uma vez que recondiciona o solo. Essa mudança pode ser favorável ou não, dependendo da cultura a ser implantada e do solo a ser corrigido. Diante disso, realizou-se experimento com o objetivo de avaliar os efeitos do calcário, cuja quantidade foi calculada seguindo o método da incubação com CaCO3, nas características químicas de dois solos, um com textura arenosa e outro com textura argilosa. Primeiramente, foi efetuada a incubação do solo com o calcário, que foi mantido em sacolas plásticas por 40 dias, considerando os tipos de solos estudados. A quantidade de calcário dependeu das doses testadas, que foram distribuídas em delineamento inteiramente casualizado, constituindo 10 tratamentos (doses) e três repetições, sendo: 0,0; 0,5; 1,0; 2,5; 5,0; 7,5; 10,0; 12,5; 15,0 e 20,0 t ha-1. Após incubação, realizaram-se as análises químicas dos solos. A elevação das doses de calcário, aplicadas ao Latossolo Vermelho distrófico, proporcionou alterações nos teores de Ca, Mg, H, Al e Fe; que culminaram em alterações em características como pH, CTC, V% e m%, tanto quando a textura deste foi argilosa, quanto quando foi média.Palavras-chave: calagem; fração textural; CaCO3; correção do solo. METHOD OF INCUBATION WITH LIMESTONE IN THE CHEMICAL CHARACTERISTICS OF SOILS WITH DIFFERENT TEXTURES ABSTRACT: Liming interferes on the availability of nutrients, because it reconditions the soil. This change may or may not be favorable, depending on the culture to be implanted and the soil to be corrected. For this, a experiment was realized with the objective of to evaluate the effects of limestone, that the quantity was calculated using the method of incubation with CaCO3, in the chemical characteristics of two soils, one with medium texture and the other with a clayey texture. First, the soil was incubated with the limestone and the material was kept in plastic bags for 40 days, considering the types of soils studied. The amount of limestone depended on the doses tested, which were distributed in a completely randomized design, constituting 10 treatments (doses) and three replications, that were: 0.0; 0.5; 1.0; 2.5; 5.0; 7.5; 10.0; 12.5; 15.0 and 20.0 t ha-1. After incubation, analyzes of the chemical characteristics of the soils, were carried out. The increase of limestone doses, applied to the dystrophic Red Latosol, caused alterations in Ca, Mg, H, Al and Fe contents; culminating in changes in characteristics as pH, CTC, V% and m%, when the texture was clayey and medium.Keywords: liming; fraction textural; CaCO3; soil correction.

During storage, many apple (Malus ×domestica Borkh.) genotypes lose their desirable textural qualities, but some like `Honeycrisp', maintain their sensory Crispness and Firmness. To understand this differential response of genotypes to postharvest changes in texture, reliable and quantifiable methods of texture measurement are needed. This study integrated data from a snapping test, confocal laser scanning microscopy (CLSM), and sensory panels to study postharvest textural changes and to predict sensory textural attributes of Firmness, Crispness, Mealiness, and Juiciness. Three separate analyses on fresh, stored, and combined fresh and stored fruit data yielded different predictors for the same sensory attributes. Change in Crispness during storage was successfully predicted by change in Work during storage. Cell number and size were related to fresh fruit texture and its maintenance during storage. Unique textural properties of `Honeycrisp' were found to be inherited by its progeny.

Abstract Texture is one of the critical parameters that affect the process behavior of ore minerals. Traditionally, texture has been described qualitatively, but recent works have shown the possibility to quantify mineral textures with the help of computer vision and digital image analysis. Most of these studies utilized 2D computer vision to evaluate mineral textures, which is limited by stereological error. On the other hand, the rapid development of X-ray microcomputed tomography (µCT) has opened up new possibilities for 3D texture analysis of ore samples. This study extends some of the 2D texture analysis methods, such as association indicator matrix (AIM) and local binary pattern (LBP) into 3D to get quantitative textural descriptors of drill core samples. The sensitivity of the methods to textural differences between drill cores is evaluated by classifying the drill cores into three textural classes using methods of machine learning classification, such as support vector machines and random forest. The study suggested that both AIM and LBP textural descriptors could be used for drill core classification with overall classification accuracy of 84–88%.

Texture is an important feature that aids in identifying objects of interest or region of interest irrespective of the source of the image. In this paper, a novel and simple isopattern-based texture feature is introduced. Spatial gray scale dependencies represented by bit plane is analyzed for specific patterns and are accumulated in bins. These are scaled by half-normal weighting function to provide isopattern texture feature. The ability of this texture feature in capturing textural variations of the images despite the presence of illumination, scale and rotation is demonstrated by conducting texture analysis on Brodatz, OuTex texture datasets and its classification accuracy on Kylberg dataset. The results of these two experimentation indicate that the proposed textural feature picks variation in texture significantly and has a better texture classification accuracy of 98.26% when compared with the state-of-the-art features like Gabor, GLCM and LBP.

Although textural information can be used to estimate vegetation biomass, its use for estimating crop biomass is rare, and previous methods lacked a mechanistic explanation for the relationship to biomass. The objective of the present study was to develop mechanistic textural indices for estimating cotton biomass and solving saturation problems at medium and high biomass levels. A nitrogen (N) fertilization experiment was established, and unmanned aerial vehicle optical images and field measured biomass data were obtained during critical cotton growth stages. Based on these data, two textural indices, namely the normalized difference texture index combining contrast and the inverse difference moment of the green band (NBTI (CON, IDM)g) and normalized difference texture index combining entropy and the inverse difference moment of the green band (NBTI (ENT, IDM)g), were proposed by analyzing the mechanism of texture parameters for biomass prediction and the law of texture parameters changing with biomass. These indices were compared with spectral indices commonly used for biomass estimation using independent validation data, such as the normalized difference vegetation index (NDVI). The results showed that the proposed textural indices performed better than the spectral indices with no saturation problems occurring. The combination of spectral and textural indices using a stepwise regression method performed better for biomass estimation than using only spectral or textural indices. This method has considerable potential for improving the accuracy of biomass estimations for the subsequent delineation of precise cotton management zones.

A low carbon steel (0.07-wt % carbon) sheet metal was deformed in five different strain paths, from equi-biaxial tension to plane strain to near uniaxial tension, by in-plane stretching. Textural developments were characterized by X-ray Orientation Distribution Function (ODFs) and the same were simulated using different Taylor type deformation texture models. A strong difference in bulk texture developments was observed at respective strain paths. The textural differences largely explain the changes observed in normal anisotropy values obtained by mechanical testing. The new deformation texture simulation model, Lamel, was quite successful in predicting quantitatively such textural differences. Microscopically, the significant features of the substructures were “strain localizations”—first generation dense dislocation walls (DDWs) and micro bands (MBs). Both in-grain rotations and estimated stored energies did depend on the relative appearance of such strain localizations. These, on the other hand, were distinctly related to the textural softening or dM/dε, where M and ε are the Taylor factor and true strain, respectively.

The energy consumed in the process of comminution highly depends on the mechanical properties of the materials being ground, which is controlled by the constituent minerals, their relative abundance and the texture. The quantitative description of textural information is essential in determining which textural characteristics can be attributed to certain mineral processing behaviours. The researcher’s opinions on the effect of different textural elements on the grindability differ. A correlation which can attribute numerical crushability and grindability values to certain textural features have not been established yet, however some general conclusions can be drawn. The effect of the mineralogical constitution is negligible, but the variation in hardness and the texture has a great impact.

The 3D reflection seismic response is associated with a zone (the Fresnel zone), rather than with a single point used in the idealized 1D convolution model. Unlike a point of incidence, the Fresnel zone is complicated by its textural characters that are defined by the dip and azimuth of microreflectors in the zone. The Fresnel-zone texture makes seismic amplitude interpretation more complicated than previously documented. A conceptual model suggests that seismic amplitude variations with offset (AVO), azimuth (AVAz), and frequency (spectral decomposition) were physically related to textural roughness, textural anisotropy, and textural scale of the Fresnel zone, respectively. Textural roughness is defined by the dip deviation of microreflectors and contributes to the AVO intercept and gradient. Textural anisotropy is defined by the degree of the preferred orientation of the microreflectors and directly affects the AVAz signature. Textural scale is defined by the spacing of the microreflectors and controls the selective frequency tuning in spectral decomposition data. The Fresnel-zone texture gives rise to amplitude variations that can not be accurately modeled by using a 1D reflectivity-wavelet convolution algorithm, and thus poses challenges to the reliability of many previous predictions of rock properties and thickness from amplitude. The AVO, AVAz, and spectral decomposition data should be used to characterize Fresnel-zone texture for predicting depositional facies, deformational fabrics, and hydraulic properties in the subsurface.

The intellectual history of the ancient philosophical “Masters” depends to a large extent on accounts in early historiography, most importantly Sima Qian’s Shiji which provides a range of longer and shorter biographies of Warring States thinkers. Yet the ways in which personal life experiences, ideas, and the creation of texts are interwoven in these accounts are diverse and uneven and do not add up to a reliable guide to early Chinese thought and its protagonists. In its selective approach to different thinkers, the Shiji under-represents significant parts of the textual heritage while developing several distinctive models of authorship, from anonymous compilations of textual repertoires to the experience of personal hardship and political frustration as the precondition for turning into a writer. L’histoire intellectuelle des “maîtres” de la philosophie chinoise ancienne dépend pour une large part de ce qui est dit d’eux dans l’historiographie ancienne, tout particulièrement le Shiji de Sima Qian, qui offre une série de biographies plus ou moins étendues de penseurs de l’époque des Royaumes Combattants. Cependant leur vie, leurs idées et les conditions de création de leurs textes se combinent dans ces biographies de façon très inégale, si bien que l’ensemble ne saurait être considéré comme l’équivalent d’un guide de la pensée chinoise ancienne et de ses auteurs sur lequel on pourrait s’appuyer en toute confiance. Dans sa façon d’approcher sélectivement les différents penseurs, le Shiji tend à sous-représenter des secteurs significatifs de l’héritage textuel; en même temps il développe plusieurs modèles distinctifs de rapport entre texte et auteur, depuis la compilation anonyme de répertoires textuels jusqu’à l’expérience du malheur et à la frustration politique posées comme conditions pour devenir écrivain.

This paper describes two examples of real-life applications of texture segmentation using M-band wavelets. In the first part of the paper, an efficient and computationally fast method for segmenting text and graphics part of a document image based on textural cues is presented. It is logical to assume that the graphics part has different textural properties than the non-graphics (text) part. So, this is basically a two-class texture segmentation problem. The second part of the paper describes a segmentation scheme for another real-life data such as remotely sensed image. Different quasi-homogeneous regions in the image can be treated to have different texture properties. Based on this assumption the multi-class texture segmentation scheme is applied for this purpose.

This article proposes the social sciences consider texture – rather than text − as the important legacy of the ‘cultural turn’ in the social sciences. The article considers texture in the literal sense of surface-patterns, as well as texture as a metaphor for the ‘dynamic’ and hard-to-capture qualities of social life. The article draws on the philosopher Stephen C. Pepper and the anthropologist Tim Ingold, the ‘practice turn’ in organizational studies and recent developments in geography and cultural research to map out different textural frameworks. While sociologists have lagged behind their counterparts in other fields in embracing a textural sensibility, the article considers the writings of Georg Simmel and the Yale School of Cultural Sociology as prominent exceptions to that rule. The article concludes by encouraging sociologists to consider the textural as a way into a ‘theoretical’ – as against a purely ‘methodological’ conception – of the qualitative.

While image texture is effective for use in pattern-recognition and image-analysis algorithms, textural features are time-consuming to calculate on standard CPUs. Therefore, we present novel implementations of textural-feature algorithms on graphics processors (GPUs), enabling fast color and texture analysis. Since different textural-feature calculations exhibit diverse characteristics, we focus on using general and algorithm-specific techniques to exploit the inherent parallelism and computational power of a GPU. Common operations required during the textural-feature pipeline range from streaming computations to recursive procedures, from arithmetically intensive transcendental functions to matrix operations. Some of these kernels are well-suited to GPUs, while others require considerable programming effort to fully exploit the memory hierarchy due to their memory-usage patterns. In this paper, different strategies for computing textural features on GPUs are compared with counterpart implementations on multicore CPUs, and experimental results show GPU results reaching a speedup of 500 times for certain operations.

The current study was conductedas a pot experiment to determine the effect of soil texture on biological nitrogen fixation (BNF) of six most efficient local isolates, specified, of Bradyrhizobium. Cowpea (Vignaunguiculata L.), as a legume host crop, was used as a host crop and 15N dilution analysis was used for accurate determination of the amount of N biologically fixed under experimental parameters specified. Soils used are clay loam, sandy clay loam and sandy loam. Biological Nitrogen Fixation (BNF), in different soil textural classes, was as in the following order: medium texture soil > heavy texture soil > light textured soil. Statistical analysis showed that there is a significant variation in BNF % among six Iraqi isolates in the three soil textural classes. There is a significant variation in the number of the nodules of the six Isolates in one soil texture. However, nodules number does not agree with the BNF% in the same soil for any isolates. Statistical analysis of the data showed that there were significant differences in plant dry weight among the soil textural classes all over local isolates used in this study. Data also showed that there were significant differences in dry weight under different isolates.

<p>Um dos dilemas recorrentes na sociologia da arte tem sido como balancear abordagens <em>internalistas</em> e <em>externalistas</em> dos fenômenos estéticos (isto é, explicações estéticas e sociais); ou o que este artigo caracteriza como a necessidade de sair de um modelo “<em>ou arte ou sociedade”</em> para um modelo de lógica “<em>tanto arte quanto sociedade</em>”. Nos últimos anos, os dilemas conceituais foram intensificados por uma tendência de o capitalismo se tornar um fenômeno mais explicitamente cultural. Ao mesmo tempo, os conhecimentos sobre arte e estética saíram da esfera da <em>grandiosidade</em> e da alta cultura para o mundo prosaico do dia a dia. Este artigo propõe que a solução para os dilemas em curso da sociologia da arte, e para o atual desafio das bases da arte e do conhecimento estético é adotar um paradigma textural, ao invés de um modo de pensar textual. O paradigma textural foi desenvolvido primeiramente no pensamento sobre lugar e é adequado para pensar os problemas da sociologia da arquitetura e do urbanismo – incluindo o problema de como o tecido urbano, às vezes, começa a desemaranhar; ou porque alguns estilos arquitetônicos improváveis voltam à moda (como, por exemplo, o brutalismo pós-guerra).</p><p>BOTH-AND: ON THE NEED FOR A ‘TEXTURAL’ SOCIOLOGYOFART</p><p><strong>Abstract</strong></p><p>One of the recurring dilemmas in the sociology of art has been how to balance ‘internalist’ and ‘externalist’ accounts of an esthetic phenomena (i. e., a esthetic and social explanations); or, what this paper terms the necessity of moving from an either-or model of art and society to adopting a both - and logic. In the last few years, the conceptual dilemmas have been further heightened by developments such as capitalism becoming more explicitly cultural; and knowledges about art and aesthetics moving from there almof the ‘grand’ and the high cultural to the more prosaic and the every day. This paper proposes that a solution to the ongoing dilemmas of the sociology of art, and the current challenge of the proliferation of arts/aesthetics-knowledge bases, is to adopt a textural rather than textural mode of thinking. The textural paradigm was first developed in thinking about place and is well-suited to thinking through problems in the sociology of architecture and urbanism – including the problem of how the urban fabric, at times, starts to unravel; or why some unlikely architectural stillest age comebacks (e. g., post-war brutalism).</p><p>Keywords: textures; sociology of art; Ingold; Lefebvre; architecture and urbanism.</p><p><strong> </strong></p><p>SUR LA NECESSITE D'UNESOCIOLOGIE DE LA TEXTURE DE L'ART</p><p class="Standard"><strong>Resumé </strong></p><p class="Standard">L'un des dilemmes le plus récurrent dans la sociologie de l'art c'est de savoir comment équilibrer les approches internalistes et externalistes des phénomènes esthétiques (c'est-à-dire des explications esthétiques et sociales); ou ce que cet article définit comme la nécessité de sortir d'un modèle «d'un art ou d'une société» pour un modèle logique «à la fois l'art et société».

Fruit textural characteristics can affect the storage, transportation, and processing of plum (Prunus salicina Lindl) in commercial production. We analyzed 23 plum cultivars with marked differences in fruit traits. Basic physicochemical indicators and textural characteristics of the fruits were determined using puncture testing and texture profile analysis. Furthermore, through the combined application of cluster analysis and principal component analysis, the indexes were simplified to three relatively independent dimensions, comprehensively reflecting the hardness, size, and flexibility of plum fruit. Our results show a high positive correlation among textural characteristics such as hardness, springiness, gumminess, and chewiness, whereas toughness and brittleness were negatively correlated. In addition, physicochemical properties were correlated to the texture traits. The weight and size of the plum fruit were related to hardness, adhesiveness, and chewiness. The soluble solids and water content contributed to the hardness, cohesiveness, and resistance to chewing. Cluster analysis revealed three distinct clusters: Cluster I represented by ‘Meiguihong’ with high hardness and a chewable texture; Cluster II represented by ‘Siyuecui’, ‘Cuimi’, and ‘Qingcui’ with a hard and brittle texture; and Cluster III represented by ‘Jinmi’, ‘Taoli’, and ‘Oishiwase’ with a soft and tough texture. The results of this study provide a significant theoretical foundation for quality evaluation, and classification of plum fruit characteristics, thus providing insights for further breeding of plum varieties.

This paper investigated the friction and wear behaviors of nylon rubbing against steel discs with helical, parallel and multidirectional textures respectively. The results indicated that friction coefficient, friction temperature and wear rate of couple using helical texture steel disc as counterpart were higher than others. Abrasive wear was the primary mechanism of the three couples. Nylon surface roughness increased after rubbing against helical texture steel disc, but decreased after rubbing against parallel and multidirectional texture steel discs. The roughness of both helical and multidirectional texture steel discs increased slightly after test, while the roughness increase of parallel textual steel disc was significant only at regions perpendicular to the rotating direction due to adhesion of nylon transfer film.

The quantitative evaluation of images taken during biofilm experiments is an important step in determining the relation between biofilm performance and biofilm architecture. Whereas areal descriptors are used by some researchers, descriptors of biofilm texture have received limited attention. In our research, the texture of images documenting long-term biofilm experiments was evaluated using a spatial grey level dependence matrices (SGLDM) approach. By calculating SGLDM for a wide range of position operators (angle–distance combinations), the discriminatory power of this approach was extended. For some descriptors, surface plots allowed the direct spatial interpretation of texture. Using principal component analysis (PCA) a subset of independent textural descriptors was identified. It is suggested to determine textural fingerprints of stages during biofilm development by making use of PCA and biplots.

Abstract. The soil texture representation with the standard textural fraction triplet sand–silt–clay is commonly used to estimate soil properties. The objective of this work was to test the hypothesis that other fraction sizes in the triplets may provide a better representation of soil texture for estimating some soil parameters. We estimated the cumulative particle size distribution and bulk density from an entropy-based representation of the textural triplet with experimental data for 6240 soil samples. The results supported the hypothesis. For example, simulated distributions were not significantly different from the original ones in 25 and 85 % of cases when the sand–silt–clay and very coarse+coarse + medium sand − fine + very fine sand − silt+clay were used, respectively. When the same standard and modified triplets were used to estimate the average bulk density, the coefficients of determination were 0.001 and 0.967, respectively. Overall, the textural triplet selection appears to be application and data specific.

The quantitative relationships among chemical composition, storage temperature, and texture of cheese were not fully understood. In this study, the effects of composition and temperature on textural properties of eight common varieties of sliced cheese were examined. The textural properties of sliced cheeses, including firmness, cohesiveness, adhesiveness, springiness, chewiness, and resilience, were measured by texture profile analysis after storage at 4 and 25°C for 4 h. Multivariate logistic regression models were established to describe the quantitative relationships of textural properties (dependent variables) to chemical composition and storage temperature (independent variables) of sliced cheeses. Results showed that protein, fat, moisture, and sodium chloride contents as well as storage temperature significantly affected the texture of sliced cheeses (P<0.05). In particular, fat in the dry matter and moisture in the nonfat substances were negatively correlated with firmness of sliced cheeses (P<0.05). As storage temperature rose from 4 to 25°C, the average values of firmness, chewiness, and resilience substantially declined by 42%, 45%, and 17%, respectively (P<0.05). This study provided reference data for adjusting chemical composition and storage temperature of common cheese products to obtain favorable texture for Chinese consumers, which thereby facilitated the localization of cheese industry in Chinese market.

Industrially processed doped-tungsten wires in the as-drawn condition have essentially a <110>-fibre texture with attractive mechanical properties. The main objectives of the present work are to investigate (I) if any textural changes occur as the wire diameter decreases and (II) if such changes influence the mechanical behaviour of the wire. A wire of about ∅1.5mm is drawn to about ∅0.15mm following a standard industrial route and samples were collected from five intermediate drawing passes. Bulk texture measurements using X-radiations were then carried on the transverse sections of the wires and texture characteristics such as volume fraction of textural components and sharpness index were quantified with respect to the wire diameter. It was observed that the texture in the as-drawn wires remains chiefly the same <110>-fibre as the wire diameter decreases. However, the sharpness of texture reaches a maximum at a certain diameter and decreases with further decrease in the wire diameter. An explanation is offered based on the concept of deformation zone geometry. An attempt was also made to determine if texture weakening has any effect on the mechanical properties of the wire at room temperature.

This essay demonstrates that texture can act as a form-defining factor by focusing on one specific textural type: imitative polyphony. Mozart’s six quartets dedicated to Haydn illustrate this claim. Building on William Caplin’s form-functional theory and his distinction between tight-knit and loose organization, imitative texture is shown to serve two purposes: as a loosening device, and as a means of textural and phrase-structural contrast. To deepen our understanding of polyphony’s formal and expressive roles, two new concepts are proposed: contrast pair and imitative presentation. The contrast-pair principle is then explored in select Viennese quartets by Mozart’s contemporaries.

Soil texture is an independent and innate soil property and other dynamic soil properties such as electrical conductivity (EC), organic carbon (OC) content and cation exchange capacity (CEC) are mostly dependent on it. An attempt was made to develop a model for numerically simulating soil texture and also to construct relationships of the developed model with other soil properties. Hypothetical data of particle size distribution and our data were used to justify and validate the newly defined indices. Scatter diagrams showed good association between the indices and hypothetical data of soil separates. Moreover, similar trends were observed between the line charts of USDA soil textural class codes and the indices. Strong correlations (r = 0.78–0.96) were found between the indices and soil separates (sand, silt and clay) for our data. However, the indices demonstrated moderate correlations (r = –0.34 to –0.55) with EC and OC of the soils. Strong nonlinear relationships were found between CEC and the three indices (R2 = 0.699, R2 = 0.732 and R2 = 0.672 (all P < 0.001). Furthermore, the variability of EC, OC and CEC within a single USDA textural class and customised textural index groups were described using the developed model. The developed indices showed excellent fitness for simulation of soil texture and demonstrated an extended applicability in terms of their relationships with soil properties related to soil texture, which will help in constructing digital soil maps.

The aim of this study was to examine whether additional digital intraoral radiography (DIR) image preprocessing based on textural description methods improves the recognition and differentiation of periapical lesions. (1) DIR image analysis protocols incorporating clustering with the k-means approach (CLU), texture features derived from co-occurrence matrices, first-order features (FOF), gray-tone difference matrices, run-length matrices (RLM), and local binary patterns, were used to transform DIR images derived from 161 input images into textural feature maps. These maps were used to determine the capacity of the DIR representation technique to yield information about the shape of a structure, its pattern, and adequate tissue contrast. The effectiveness of the textural feature maps with regard to detection of lesions was revealed by two radiologists independently with consecutive interrater agreement. (2) High sensitivity and specificity in the recognition of radiological features of lytic lesions, i.e., radiodensity, border definition, and tissue contrast, was accomplished by CLU, FOF energy, and RLM. Detection of sclerotic lesions was refined with the use of RLM. FOF texture contributed substantially to the high sensitivity of diagnosis of sclerotic lesions. (3) Specific DIR texture-based methods markedly increased the sensitivity of the DIR technique. Therefore, application of textural feature mapping constitutes a promising diagnostic tool for improving recognition of dimension and possibly internal structure of the periapical lesions.

Abstract Due to their soft texture consumers prefer moist figs, which has motivated fig processors to increase the production of this product. However, as water enhances the browning reaction rate, moisture content optimisation of moist figs is very important. Processed figs must have suitable texture softness with browning kept to a minimum. The purpose of this study was to examine the effect of moisture content on the textural attributes of dried figs. Hardness, compression energy, gradient, gumminess and chewiness of fig samples decreased with moisture content exponentially, whereas the trend of springiness and cohesiveness with change of moisture content was nearly constant. Moreover, in the texture profile analysis plot of rehydrated figs, the presence of negative area is an indication of adhesiveness which was zero in control dried figs. The results of the texture profile analysis tests proved the existence of a critical moisture content of about 18.4%, above which no significant effect of moisture content on textural parameters was found. The glass-rubber transition results from differential scanning calorimeter may explain the different texture profile analysis attributes of dried figs compared with rehydrated figs.

Abstract Gray Level Co-Occurrence Matrix (GLCM), as a measure of spatial features has been used as supplemental information to improve image classification accuracy for lithological recognition. Window size is an important parameter for texture extraction, which will affect the extracted texture results. Besides, the existence of mixed pixels in image usually causes errors in test samples, which significantly influences the credibility of accuracy assessment. Thus, this paper proposes a lithological classification method combined with optimal texture window size selection and test sample purification. Firstly, optimal window size pre-estimated based on semivariogram was used to calculated GLCM texture of image. Secondly, based on multidimensional textural and spectral features, a support vector machine (SVM) classifier was employed to classify the image. Thirdly, using the proposed sample purification method and textural features of image, sample purification rules were created based on attribute coherence to remove the test sample points that conflicted with the rules. Finally, the validity of the semivariogram-based texture extraction window selection was verified by classifications based on Angular Second Moment (ASM) of different window sizes combined with spectral features. Also, the accuracies between different combinations of classifications were assessed by test samples with and without sample purification. Experimental results show that the pre-estimated texture window size can guarantee a classification result with high classification accuracy for lithological classification. The results also demonstrated that the accuracy of lithological classification based on spectral features and ASM textural features was the highest. The overall lithological classification accuracy and kappa value, without sample purification selected by stratified sampling, were respectively 87.4% and 0.84, however those with sample purification were respectively 88.01% and 0.85. The results show that the proposed method is capable of yielding more reliable lithostratigraphic identification.

SummaryThe relationships between the composition, texture and microstructure of chhana (an Indian-style soft cottage cheese analogue) and rasogolla (a sweetened dairy product made from chhana) were analysed. Chhana contained a significantly higher proportion of fat, protein, lactose and minerals than did rasogolla. Cooking of chhana in 60% sucrose solution introduced sucrose and changed the texture and structure to that typical of rasogolla. As chhana was transformed to rasogolla, the Instron textural properties, hardness, gumminess and chewiness, fell significantly, whereas springiness increased dramatically. Market rasogolla had a slightly different composition from the laboratory-made samples, but both had similar Instron textural and sensory textural attributes. Scanning electron microscopy showed that chhana had a structure like cottage cheese or cream cheese, a compact, coalesced casein matrix with fat globules embedded in it. Rasogolla had a conglomerated, ragged and porous casein matrix with uneven surface and numerous large void spaces. The collapsed and ruptured fat globules were found embedded in the agglomerated protein particles of rasogolla. The textural attributes of both chhana and rasogolla could be explained by the microstructure.

The effect of the hot rolling speed on the textural and structural state of 6061aluminum alloy sheet was investigated. The final deformation temperature allows avoiding the development of recrystallization processes due the decrease of rolling speed. The heterogeneity of the texture state is provided for by the differences in stress conditions for semifinished rolled plate. The deformation texture of the central layer of the hot-rolled sheet corresponds to the stable orientations of the rolling texture of the fcc material. The deformation texture of the surface area generally corresponds to the shear texture of the material with fcc lattice. The recrystallization texture is more scattered, however its component composition is the same as for the deformation texture, but the main orientations can either be maintained of varied.

Abstract The objective of this study was to examine whether the Polish soil textural classification is useful for evaluation of soil water retention and hydraulic properties and, furthermore, for determining which textural classes are characterized by the highest diversity of soil water retention and hydraulic properties. The texture triangle was divided into a 1% grid of particle-size classes resulting in 5151 different data points. For each data point, soil water retention parameters and saturated hydraulic conductivity were obtained using the ROSETTA program. The silt classes showed the highest uncertainty in the estimation of the saturated water content based on the soil texture. These classes are characterized by high variations of saturated water content within the class. Estimations of field capacity and permanent wilting point on the basis of textural classes are encumbered with highest errors for gp, pg, pl and pyg soils, which are characterized by the highest values of coefficient of variation. Saturated soil hydraulic conductivity is better classified into homogeneous classes by the Polish texture classes than by the clusters obtained by the k-means cluster analysis based on the soil hydraulic and retention properties. Soil water retention parameters are better classified into homogeneous groups by the k-means cluster analysis than by the traditional textural classes. Cluster analysis using the k-means can be helpful for grouping similar soils from the point of view of their retention properties.

Traditional approaches for texture segmentation via wavelet transform usually adopt textural features to achieve segmentation purposes. However, for a natural image, the characteristics of the pixels in a texture region are not similar everywhere from a global viewpoint, and over-segmentation often occurs. To deal with this issue, an unsupervised texture segmentation method based on determining the interior of texture regions is proposed. The key idea of the proposed method is that if the pixels of the input image can be classified into interior pixels (pixels within a texture region) and boundary ones, then the segmentation can be achieved by applying region growing on the interior pixels and reclassifying boundary pixels. Based on the fact that each pixel P within a texture region will have similar characteristics with its neighbors, after applying wavelet transform, pixel P will have similar response with its neighbors in each transformed subimage. Thus, by applying a multilevel thresholding technique to segment each subimage into several regions, pixel P and its neighbors will be assigned to the same region in most subimages. Based on these segmented results, an interior pixels finding algorithm is then provided to find all interior pixels of textural regions. The algorithm considers a pixel which is in the same region as its neighbors in most subimages as an interior pixel. The effectiveness of this method is proved by successfully segmenting natural texture images and comparing with other methods.

The magnetic properties of ferromagnetic materials are closely related to the crystallographic texture, i.e. the orientation distribution of the crystallites, they are, however, not uniquely determined by the texture. Higher order “textural quantities” such as, for instance, orientation correlation functions are additionally needed for a more complete description.The properties in saturation are uniquely determined by the texture. They can be expressed by a fourth—or sixth—order approximation of the texture function which can be obtained by “low resolution” texture measurements.On the other hand, magnetic anisotropy measurements can only provide a low-resolution approximation to the texture function and not the complete function.The distribution of magnetization directions can be described by a “magnetic texture” which can be calculated from pole figures measured by neutron diffraction using the method of superposed pole figures.

The paper presents a comparison of the efficacy of several texture analysis methods as tools for improving land use/cover classification in satellite imagery. The tested methods were: gray level co-occurrence matrix (GLCM) features, Laplace filters and granulometric analysis, based on mathematical morphology. The performed tests included an assessment of the classification accuracy performed based on spectro-textural datasets: spectral images with the addition of images generated using different texture analysis methods. The class nomenclature was based on spectral and textural differences and included the following classes: water, low vegetation, bare soil, urban, and two (coniferous and deciduous) forest classes. The classification accuracy was assessed using the overall accuracy and kappa index of agreement, based on the reference data generated using visual interpretation of the images. The analysis was performed using very high-resolution imagery (Pleiades, WorldView-2) and high-resolution imagery (Sentinel-2). The results show the efficacy of selected GLCM features and granulometric analysis as tools for providing textural data, which could be used in the process of land use/cover classification. It is also clear that texture analysis is generally a more important and effective component of classification for images of higher resolution. In addition, for classification using GLCM results, the Random Forest variable importance analysis was performed.
