Abstract (sommario):

What is a photograph? What a spurious, redundant start! After all, a photograph is clearly an image, a technical image of something. What a photograph is – such a stupid question! Yet, the casual announcement of the photograph as signification relies on an a priori truth that orients our thinking, our identities, our institutions. For it is “in terms of this self-apparent image of thought that everybody knows and is presumed to know what it means to think.” Collaging Deleuze and Bergson, intuition teaches us that an image is a nexus of force in itself, or as Anne Sauvagnargues suggests, what is crucial to images is how they cut into the world. As real enfoldings of the virtual and actual, photographs are the territories of a multiplicity of sensations – a genesis, the real actual of a diagrammatic structuring of the world in registers of time and space. Roger Fenton’s The Queen’s Target made at Queen Victoria’s opening of the first Rifle Association in 1860 is an entry point to thinking deeper signalisation in photographs. While the 3-D work by Andreas Angelidakis indicates photogenetic zones of intensity, temporal dislodgment, and the event of photogenesis actualized in physical form. Keywords: photogenesis, virtual, photography and event, ontology of the image, photography and information, philosophy of photography

Abstract (sommario):

Fashion photographs are generally two-dimensional images showing one side of a three-dimensional model. This paper, however, deals with far less well-known stereoscopic fashion photographs. Stereoscopy is a technique that creates the illusion of a 3-D image. Based on the image collection of Swiss textile and clothes company HANRO, the article analyzes the composition of 3-D pictures by putting them in a broader media-historical context. The archived stereoscopic photographs date back to the 1950s and show a series of women’s fashion. In the same period, Hollywood experienced a 3-D-boom that may have had a technical and aesthetical impact on these photographs. Although fashion is not mediated in moving images in this case study, codes or formal languages of a film are inscribed in the images, as will be shown in the following text. Building on these findings, this paper further discusses the influence of cinematography and other media practices on the fashion industry’s attempt to free its fashion imagery from the confines of a two-dimensional page.

Abstract (sommario):

Yes
The Molecular Stress Function (MSF) constitutive model with convective constraint release mechanism has been shown to accurately fit a large range of viscometric data, and also shown to give strong vortex growth in flows of LDPE through planar and axisymmetric contractions. This work compares simulation and experimental results for 3-D flows of Lupolen 1840H LDPE through a contraction slit; 3-D effects are introduced by using a slit with a low upstream aspect ratio of 5:3. Comparisons are made with vortex opening angles obtained from streak photography, and also with stress birefringence measurements. The comparisons are made with two versions of the convective constraint release (CCR) mechanism. The simulated vortex angles for one version of the CCR mechanism are found to approach what is seen experimentally. The best-fit value for the stress optical coefficient was found to vary between CCRs and to decrease with flow rate. This is partially explained by different centreline elongational rates with the two CCRs, which in turn is related to different opening angles. A 3-D simulation is compared to the corresponding 2-D simulation. It is shown that both velocity vectors and birefringence show only small changes to around 60% of the distance to the side wall.

The main objective of this thesis named The role of photography in hypermedia is to investigate the characteristics that photography acquires when it is integrated into the context of hypermedia. The point of departure is the technical history of photography and the transmutations it is undergoing in the digital world. Then, photography is studied as a language. The method that was applied was to identify the technical and stylistic devices of photography such as plane, ground, focus, movement, angles, illumination, perspective and others. The same procedure was followed concerning hypermedia, a hybrid language which, thanks to the digital process, the speranto of machines, is structured in a mixture of several languages, photography among them. In the end, the role of photography in hypermedia was studied in light of the evolution in the modes of production of the image with an emphasis in 3D computational image

Parte-se da história técnica da fotografia e as transmutações por que vem passando no mundo digital, para, então, estudá-la como linguagem. O método utilizado para isso foi o da identificação de seus recursos técnico-estilísticos, tais como: plano, foco, movimento, ângulo, iluminação, perspectivas entre outros. O mesmo se fez com a hipermídia, uma linguagem híbrida que, graças ao esperanto das máquinas, ou seja, o processo digital, é tecida na conjugação de várias linguagens, entre elas, a fotografia. Por fim, o papel da foto na hipermídia foi estudado à luz da evolução nos modos de produção da imagem, com ênfase na imagem computadorizada 3D

Hu, Zhihong. "Multimodal 3-D segmentation of optic nerve head structures from spectral domain Oct volumes and color fundus photographs". Diss., University of Iowa, 2011. https://ir.uiowa.edu/etd/3470.

Testo completo

Abstract (sommario):

Currently available methods for managing glaucoma, e.g. the planimetry on stereo disc photographs, involve a subjective component either by the patient or examiner. In addition, a few structures may overlap together on the essential 2-D images, which can decrease reproducibility. Spectral domain optical coherence tomography (SD-OCT) provides a 3-D, cross-sectional, microscale depiction of biological tissues. Given the wealth of volumetric information at microscale resolution available with SD-OCT, it is likely that better parameters can be obtained for measuring glaucoma changes that move beyond what is possible using fundus photography etc. The neural canal opening (NCO) is a 3-D single anatomic structure in SD-OCT volumes. It is proposed as a basis for a stable reference plane from which various optic nerve morphometric parameters can be derived. The overall aim of this Ph.D. project is to develop a framework to segment the 3-D NCO and its related structure retinal vessels using information from SD-OCT volumes and/or fundus photographs to aid the management of glaucoma changes. Based on the mutual positional relationship of the NCO and vessels, a multimodal 3-D scale-learning-based framework is developed to iteratively identify them in SD-OCT volumes by incorporating each other's pre-identified positional information. The algorithm first applies a 3-D wavelet-transform-learning-based layer segmentation and pre-segments the NCO using graph search. To aid a better NCO detection, the vessels are identified either using a SD-OCT segmentation approach incorporating the presegmented NCO positional information to the vessel classification or a multimodal approach combining the complementary features from SD-OCT volumes and fundus photographs (or a registered-fundus approach based on the original fundus vessel segmentation). The obtained vessel positional information is then used to help enhance the NCO segmentation by incorporating that to the cost function of graph search. Note that the 3-D wavelet transform via lifting scheme has been used to remove high frequency noises and extract texture properties in SD-OCT volumes etc. The graph search has been used for finding the optimal solution of 3-D multiple surfaces using edge and additionally regional information. In this work, the use of the 3-D wavelet-transform-learning-based cost function for the graph search is a further extension of the 3-D wavelet transform and graph search. The major contributions of this work include: 1) extending the 3-D graph theoretic segmentation to the use of 3-D scale-learning-based cost function, 2) developing a graph theoretic approach for segmenting the NCO in SD-OCT volumes, 3) developing a 3-D wavelet-transform-learning-based graph theoretic approach for segmenting the NCO in SD-OCT volumes by iteratively utilizing the pre-identified NCO and vessel positional information (from 4 or 5), 4) developing a vessel classification approach in SD-OCT volumes by incorporating the pre-segmented NCO positional information to the vessel classification to suppress the NCO false positives, and 5) developing a multimodal concurrent classification and a registered-fundus approach for better identifying vessels in SD-OCT volumes using additional fundus information.

Abstract (sommario):

During this study two models were developed to predict growth of Pinus radiata D.Don plantations in Canterbury, New Zealand. The first, CanSPBL(1.2), is a model for whole rotations of stands owned by Selwyn Plantation Limited in Canterbury. The second model, CanSPBL(water) is a hybrid growth model for the Selwyn estate in Canterbury that incorporates an index of root zone water balance over the simulation period. An existing stand growth and yield model CanSPBL was examined using a validation dataset of PSP measurements that were not used in model fitting. Projection bias was shown for mean top height, basal area per hectare, and residual stand stocking particularly for stands at elevations exceeding 450 metres. The new model, CanSPBL(1.2) showed an increase in precision of 4 - 46% over CanSPBL(1.0) at a stand level. The components of the stand model include mean top height, basal area per hectare, stems per hectare, and diameter distribution. The mortality model was made in conjunction with managers at CanSPBL to exclude catastrophic mortality events from model projections. Data used for model fitting was filtered using a mortality index based on the -3/2 power law. An examination of this model with an independent dataset showed little apparent bias. The new model, CanSPBL(water) was developed to include an index of water balance over the simulation period. Water balance estimates were made using a sub model for root zone water balance included in the hybrid physiological model 3-PG (Landsberg and Waring, 1997). The new model showed an increase in precision of 1 - 4% over CanSPBL(1.2) at a stand level (with the exception of the model for maximum diameter which showed a decrease in precision of 0.78%) using climatic inputs that included yearly variation. However the model showed increases of precision from 0.5 to 8% (with the exception of maximum diameter again, showing a decrease in precision of 0.13%) using long term monthly average climatic inputs. The components of the stand model also include mean top height, basal area per hectare, stems per hectare, and diameter distribution. The mortality model was also fitted with a data set filtered using a mortality severity index based on the -3/2 power law to exclude catastrophic mortality events. An examination of this model with an independent dataset showed little apparent bias. Two models to predict a one sided canopy leaf area index (LAI) of radiata pine stands in the Canterbury Plains of New Zealand were also developed. The models were fitted using non-linear least squares regression of LAI estimates against stem measurements and stand characteristics. LAI estimates were derived from digital analysis of fisheye lens photography. The models were kept simple to avoid computational circularity for physiological modelling applications. This study included an objective comparison and validation of a range of model types. The models CANTY (Goulding, 1995), CanSPBL(1.2) (Pinjuv, 2005), CanSPBL-water (Pinjuv, 2005), and 3-PG (Landsberg and Waring, 1997) were compared and validated with the main criteria for comparison being each model s ability to match actual historical measurements of forest growth in an independent data set. Overall, the models CanSPBL(water), and CanSPBL(1.2) performed the best in terms of basal area and mean top height prediction. Both models CanSPBL(water), and CanSPBL(1.2) showed a slightly worse fit in predictions of stocking than did the model CANTY. The hybrid model 3PG showed a better fit for the prediction of basal area than the statistically based model CANTY, but showed a worse fit for the prediction of final stocking than all other models. In terms of distribution of residuals, CanSPBL(1.2) had overall the lowest skewness, kurtosis, and all model parameters tested significant for normality. 3PG performed the worst on average, in terms of the distribution of residuals, and all models tested positively for the normality of residual distribution.

Abstract (sommario):

The desire to enhance and make ourselves better is not a new one and it has continued to intrigue throughout the ages. Individuals have continued to seek ways to improve and enhance their well-being for example through nutrition, physical exercise, education and so on. Crucial to this improvement of their well-being is improving their ability to remember. Hence, people interested in improving their well-being, are often interested in memory as well. The rationale being that memory is crucial to our well-being. The desire to improve one’s memory then is almost certainly as old as the desire to improve one’s well-being. Traditionally, people have used different means in an attempt to enhance their memories: for example in learning through storytelling, studying, and apprenticeship. In remembering through practices like mnemonics, repetition, singing, and drumming. In retaining, storing and consolidating memories through nutrition and stimulants like coffee to help keep awake; and by external aids like notepads and computers. In forgetting through rituals and rites. Recent scientific advances in biotechnology, nanotechnology, molecular biology, neuroscience, and information technologies, present a wide variety of technologies to enhance many different aspects of human functioning. Thus, some commentators have identified human enhancement as central and one of the most fascinating subject in bioethics in the last two decades. Within, this period, most of the commentators have addressed the Ethical, Social, Legal and Policy (ESLP) issues in human enhancements as a whole as opposed to specific enhancements. However, this is problematic and recently various commentators have found this to be deficient and called for a contextualized case-by-case analysis to human enhancements for example genetic enhancement, moral enhancement, and in my case memory enhancement (ME). The rationale being that the reasons for accepting/rejecting a particular enhancement vary depending on the enhancement itself. Given this enormous variation, moral and legal generalizations about all enhancement processes and technologies are unwise and they should instead be evaluated individually. Taking this as a point of departure, this research will focus specifically on making a case for ME and in doing so assessing the ESLP implications arising from ME. My analysis will draw on the already existing literature for and against enhancement, especially in part two of this thesis; but it will be novel in providing a much more in-depth analysis of ME. From this perspective, I will contribute to the ME debate through two reviews that address the question how we enhance the memory, and through four original papers discussed in part three of this thesis, where I examine and evaluate critically specific ESLP issues that arise with the use of ME. In the conclusion, I will amalgamate all my contribution to the ME debate and suggest the future direction for the ME debate.

Testo completo

Abstract (sommario):

The Enigma of Appearances is an examination into the medium of three-dimensional photography, with particular focus on the technique of stereoscopy. Invented in the mid-Victorian era, stereoscopy was an attempt to simulate natural three-dimensional perception via a combination of optics, neurology, and a pair of dissimilar images. Whilst successful in producing a powerful illusion of spatial depth and tangibility, the illusion produced by stereoscopy is anything but ??natural??, when compared to three-dimensional perception observed with the naked eye. Rather, stereoscopic photography creates a strange and unnatural interpretation of three-dimensional reality, devoid of atmosphere, movement and sound, where figures appear frozen in mid-motion, like waxwork models, or embalmed creatures in a museum. However, it is precisely stereoscopic photography??s unique and enigmatic interpretation of three-dimensional reality, which gives it its strength, separating it from being a mere ??realistic?? recording of the natural world. This thesis examines the unique cultural position that stereoscopy has occupied since its invention in 1838, from its early role as a tool for the study of binocular vision, to its phenomenal popularity as a form of mass entertainment in the second half of the 19th century, to its emergence in contemporary fine art practice in the late 20th and 21stt centuries. Additionally, The Enigma of Appearances gives a detailed analysis of the theory of spatial depth perception; it discusses the dichotomy between naturalia versus artificialia in relation to stereoscopic vision; and finally, traces the development of experimental studio practice and research into stereoscopic photography, undertaken for this MFA between 2005 and 2007. The resulting work, Camera Mortuaria (Italian for ??Mortuary Room??), is a powerful and innovative series of anaglyptic portraits, based upon an experimental stereoscopic technique that enables the production of extreme close-up three-dimensional photography. Applying this technique to the reproduction of the human face in three-dimensional form, Camera Mortuaria presents a series of ??photo sculptures??, which hover between reality and illusion, pushing the boundaries of stills photography to the limit, and beyond.

The major purpose of this research is to find a fast way to measure a 3-D image. The 3-D coordinates corresponding to the image caught in 1/30 can be calculated in order to be used in reverse engineering. The system consists of two CCDs, two face lasers, and one line laser. The corresponding 3-D coordinates is obtained by calculating the geometric relationship between the projected lines and CCDs. Besides, the laser lines are grouped by searching laser lines in order to use the number of the face lasers as a constraint to solve the correspondence problem of the face lasers. Finally, a four degree matrix is used to solve the problem about the transferring relationship of 3-D coordinates and the image overlapping.

Abstract (sommario):

Using new commentary from the people behind the lens blended with revealing photographs, this chapter examines the visual narrative of Bitches Brew. Although the sessions were never shot, Miles Davis was photographed just about everywhere else at the time, whether it was on stage, at home, at the gym, or driving around New York in his Ferrari. Despite his shy and difficult demeanor, Davis had a warm and sincere relationship with the camera and the people behind it. These photographers were not only able to document this period in Davis’s life, but were also able to unveil a whole other side of him.

Abstract (sommario):

The process of creating photorealistic 3-dimensional computer graphic (3DCG) images is divided into two stages: modeling and rendering. Automatic rendering has gained popularity, and photorealistic rendering is generally used to render different types of images. However, professional artists still model characters manually. Moreover, not much progress has been achieved with regard to 3-D shape data acquisition techniques that can be applied to facial modeling. This is an important problem hampering the progress of 3DCG. Generally, a laser and a highly accurate camera are used to acquire 3-D shape data. This technique is time-consuming and expensive. The eyes may be damaged during measurements by this method. In order to solve these problems, this chapter proposes a simple method for 3-D shape data acquisition using a projector and Web cameras. This method is economical, simple, and less time-consuming than conventional techniques. This chapter describes the setup of the projector and Web cameras, shape data acquisition process, image processing, and generation of a photorealistic image. As an example, the authors take a reconstructed photorealistic 3DCG image of Japanese vegetable “bitter melon,” whose surface is extremely bumpy.

Abstract (sommario):

•Stereoscopic optic nerve photography has been considered the gold standard for documenting the optic nerve head (ONH)/retinal nerve fiber layer (RNFL) status. •Digital imaging technologies were developed recently to provide reproducible and more objective quantitative assessment of the ONH and RNFL. •Each technology measures different aspects of ONH and RNFL morphology; information obtained from different imaging devices is complementary and can be used to detect different abnormal features in the same patient. •Possible roles of ONH/RNFL imaging in clinical practice: •Documentation of ONH status• Glaucoma diagnosis •Detecting progression •Risk assessment •Screening for glaucoma •CSLO is based on a method of confocal imaging. •A diode laser (670 nm) (Fig 5.1A) scans the surface of posterior pole horizontally and vertically (x- and y-axes) with high speed. Reflected light is detected by a sensor after being filtered by a confocal pinhole which is conjugate to the focal plane of the retina. •By shifting the confocal pinhole, a series of planar scans are acquired at increasing depths and after alignment are combined to create 3-D topographic map of the retina and ONH surface. •Commercially available CSLO devices with major features are listed in Table 5.1. •Image acquisition with Heidelberg Retinal Tomography (HRT) is fast; single tomographic slices are captured in only 24 ms (faster than involuntary saccades or fixation movements). •Pupillary dilation is not needed. •Good images require adequate patient positioning, good fixation, clear media, appropriate focus, and centering the optic nerve in the image. •16 to 64 planar scans are acquired per set. Unusable scans are replaced by software until three useful sets are obtained. •The operator defines the optic disc margin by drawing a contour line along scleral ring. • A reference plane is determined by the HRT software 50 μm below the average height of the contour line in the inferior temporal quadrant. All structures above the reference plane and within the contour line are defined as a neuroretinal rim and are shown as blue (sloped) and green (flat) areas on the topography image (Fig 5.2c).

Abstract (sommario):

Chapter 3 investigates the printed magazine as a site where the world of art and fashion merged in the 1980s. Since the early 1990s fashion photographs have migrated effortlessly between the art field and the commercial field, between being considered as personal works or assignments limited by the ideas and wants of designers, brands and fashion publications. As pointed out by several scholars a crucial part of this development was the new aesthetics that emerged in the 1990s which challenged traditional notions of fashion as glamorous depictions of garments, a style labelled ‘trash realism’, ’radical fashion’ or ’post fashion’. However, as the chapter shows, an equally important material basis for this development was the emergence of new fora in the 1980s. Later on, in the 1990s and early 2000s several magazines that straddled art, style culture and high fashion appeared, such as Purple Prose, Tank, 032C and Sleek. This chapter trace the beginnings of these transgressions through a close examination of the two magazines i-D and Artforum, which from different positions and with different strategies served as an active interface between art and fashion in the 1980s.

Abstract (sommario):

Students often go through the motions of sighting without really understanding what they are doing and why it works. A little understanding of the principles of sighting goes a long way toward encouraging students to use the process to their advantage. . . . Why Use Sighting? . . . Many students have found that they are shining stars when it comes to copying photographs or working from other existing two-dimensional sources. They are often confounded when they discover that drawing from observation of three-dimensional forms does not yield the same strong results, the same degree of accuracy they are accustomed to. It is helpful for both the instructor and the student to understand why this occurs. Drawing or representing a three-dimensional form on a two-dimensional surface requires, in essence, a language translation. The language of two dimensions is different from the language of three dimensions. We must observe the three-dimensional form and translate it into a language that will be effective on a two-dimensional surface, such as a piece of drawing paper. When students draw from an existing two-dimensional source, the translation from 3-D to 2-D has already been made for them. But when they are referring to the actual form, they must make the translation themselves. The process of sighting provides the method for making this translation easily and effectively. A sighting stick is the basic tool for the process of sighting. I recommend using a IO" to I2" length of 1⁄8" dowel. Suitable alternatives include a slender knitting needle, a shish-kebab skewer, or a length of metal cut from a wire clothes hanger. Your sighting stick should be straight. I discourage the use of a drawing pencil as a sighting stick simply because the thickness of the pencil often obscures information when sighting. The more slender the tool, the less it interferes with observing the form or forms being drawn. However, in the absence of a more suitable tool, a pencil will suffice. In presenting sighting principles to a class, it is vital to go beyond a verbal explanation. For students to effectively understand the process, it is strongly recommended that teacher and students walk through the process together, exploring the various ways of applying sighting.

Abstract (sommario):

Privacy uses the theory of natural rights and generally responds to new information and communication technologies. In North America, Samuel D. Warren and Louis D. Brandeis wrote that privacy is the “right to be let alone” (Warren & Brandeis, 1890) and focuses on protecting individuals. This citation was a response to recent technological developments, such as photography, and sensationalist journalism, also known as yellow journalism. Warren and Brandeis declared that information which was previously hidden and private could now be “shouted from the rooftops.” But whether the right to privacy may be limited in the case of public figures and whether public figures are accountable for their actions is up for debate. This issue is explored in this chapter through court decisions that occupied the public.

Abstract (sommario):

The experiment was conducted on the compact normal and shear (CNS) specimens made of homogeneous and dissimilar materials subjected to mixed-mode loading. Many Young’s fringes patterns around the crack tip were taken and analyzed by the image-processing system developed in my laboratory. The displacement obtained by speckle photography is not as smooth as that obtained by the finite element analysis (FEA). Therefore, the displacement data were smoothed by 2 D FFT filtering and least squares method. The intelligent hybrid method proposed by Nishioka et al. was applied to the stress-strain analysis. Consequently, the stress and strain near the crack tip can be evaluated with high accuracy by the present stress-analyzing system. Then, the stress-intensity factor was evaluated by the virtual crack extension method (VCEM) and displacement extrapolation. The accuracy of stress-intensity factor at the free surface was discussed from both viewpoint of experiment and 3 D FEA.
