Full textThis study deals with the pitfalls and standards associated with the digitisation of photographic artefacts in formal collections. The popularity of the digital medium caused a rapid increase in the demand for converting images into digital files. The need for equipment capable of executing the task successfully, the pressure on collection managers to display their collections to the world and the demand for knowledge needed by managers and operators created pressure to perform optimally and often in great haste. As a result of the rush to create digital image files to be displayed and to be preserved, the decisions that are being made may be questionable. The best choice of file formats for longevity, setting and maintaining standards to guarantee quality digital files and consultation with experts in the field of digitisation as well as attention to best practices are important aspects which must be considered. In order to determine the state of affairs in countries with an advanced knowledge and experience in the field of digitisation, a comprehensive literature study was done. It was found that enough information exists to enable collection managers in South Africa to make well informed decisions to ensure a high quality of digital collection. By means of questionnaires, a survey was undertaken amongst selected Western Cape image preservation institutions to determine the level of knowledge of the managers who are required to make informed decisions. The questionnaire was designed to give insight into choices being made regarding the technical quality, workflow and best practice aspects of digitisation. Comparing the outcome of the questionnaires with best practices and recommended standards in countries with an advanced level of experience it was found that not enough of this experience and knowledge is used by local collection managers although readily available. In some cases standards are disregarded completely. The study also investigated by means of questionnaires the perception of the digital preservation of image files by fulltime photographic students and volunteer members of the Photographic Society of South Africa. It was found that uncertainty exist within both groups with regard to file longevity and access to files in five to ten year's time. Digitisation standards are set and maintained by the use of specially designed targets which enable digitising managers to maintain control over the quality of the digital content as well as monitoring of equipment performance. The use of these targets to set standards were investigated and found to be an accurate and easy method of maintaining control over the standard and quality of digital files. Suppliers of digitising equipment very often market their equipment as being of a high quality and being able to fulfil the required digitisation tasks. Testing selected digitising equipment by means of specially designed targets proved however that potential buyers of equipment in the high cost range should be very cautious about suppliers' claims without proof of performance. Using targets to verify performance should be a routine check before any purchase. The study concludes with recommendations of implementing standards and it points to potential future research.

Full textThe quality of a telephone conversation using a VAD-based coding system depends on three major modules: the speech coder, the noise coder, and the VAD. Existing schemes for reduced-rate coding of background noise produce a signal that sounds different from the noise at the transmitting side. The frequent changes of the noise character between that produced during talk spurts (noise coded along with the speech) and that produced during speech pauses (noise coded at a reduced rate) are noticeable and can be annoying to the user.
The objective of this thesis is to develop techniques that enhance the output quality of variable-rate and discontinuous-transmission speech coding systems operating in noisy acoustic environments during the pauses between speech bursts. We propose novel excitation models for natural-quality reduced-rate coding of background acoustic noise in voice communication systems. A better representation of the excitation signal in a noise-synthesis model is achieved by classifying the type of acoustic environment noise. Class-dependent residual substitution is used at the receive side to synthesize a background noise that sounds similar to the background noise at the transmit side. The improvement in the quality of synthesized noise during speech gaps helps in preserving noise continuity between talk spurts and speech pauses, and enhances the overall perceived quality of a conversation.

Full textThis study investigates the perspective of Capetonian professional photographers on issues of integrity, regarding the impact of digital imaging technology. Key objectives are to establish how the concept of photographic integrity manifests itself throughout the history of the documentary genre, prior and subsequent to the introduction of digital imaging technology; to ascertain the extent to which the Capetonian professional photographer uses digital imaging technology compared to film technology; to discover how Capetonian professional photographers perceive various concepts related to integrity in a documentary photograph; to identify what Capetonian professional photographers regard as acceptable digital editing to the photojournalistic documentary photograph; to ascertain whether Capetonian professional photographers believe that digital imaging technology impacted on the integrity of the documentary photograph; and finally, to discern whether Capetonian professional photographers who have practiced professional photojournalism see the need for a national regulating body, which clearly makes known what acceptable picture taking (in terms of content, e.g. staging of a photograph) and digital editing entails, for the South African photojournalist. The rationale for this study is that we exist in an era where we are faced with a digital revolution which transforms perceptions of integrity and it is essential to ascertain how technology influences the perceptions of the very professionals who produce documentary photography images. The literature review evolves a context for this study. This empirical study’s data collection and analyses has a mixed-method design. The survey’s instrument of data collection is a questionnaire, which captured quantitative data and with half of one question captures qualitative data. I analysed quantitative data with the help of SPSS and I analysed qualitative data much akin to a case study. The statistical test used to analyse quantitative data is a chi-square test and there are 66 participants in the study. I found that a breach of integrity, for instance manipulation, was always possible in the era prior to the introduction of digital imaging technology. Now it is only done faster, more thorough and more people have access to editing technology. Many who lack moral fiber are tempted now, more than ever, to illicitly manipulate. Capetonian professional photographer’s experience in digital image creation and editing technology outweighs the equivalent in the film medium. Digital camera usage takes precedence over film cameras. An example of a perception of a concept related to integrity in documentary photography is the sub-group which has practiced professional photojournalism insisted (73.5% of them strongly agreed) that it is possible to be creative and truthful at the same time in documentary photography. With regard to what acceptable editing entails, for cropping respondents favoured slight cropping; for dodging and burning in respondents favoured very light dodging and burning in; for pasting in respondents favoured no pasting in is acceptable; and for removing of objects respondents favoured no removing of objects. The Capetonian professional photographer believes that digital imaging technology has impacted on the integrity of the documentary photograph. For instance, the study has measured and proved that a majority of Capetonian professional photographers believe that a documentary essay taken in film and processed in the traditional darkroom feels more consistently trustworthy than its digital equivalent. This study has shown that there is a need for a body that clearly makes known what acceptable picture taking and digital editing entails for the professional photojournalistic photographer in South Africa.

Full textTwo types of image processing methods capable of forming a composite image from a set of image slices which have in-focus as well as out-of-focus segments are discussed. The first type is based on space domain operations and has been discussed in the literature. The second type, to be introduced, is based on the intuitive concept that the spectral energy distribution of a focused object is biased towards lower frequencies after blurring. This approach requires digital image filtering in the spatial frequency domain. A comparison among methods of both types is made using a quantitative uÌ delity criterion.

Apresenta uma proposta de análise que busca justificar e demonstrar a condição da poética (Arte) da fotografia. Nesse sentido, mostra o que de incomum pode deter o olhar que eterniza e o olhar que ressuscita, dando um real valor às imagens fotográficas, sejam elas quais forem e mostrem o que de mais importante possam mostrar, mantendo as informações ao longo do tempo. Desse modo, busca contribuir para uma melhor compreensão da época em que as fotografias foram feitas, dos cenários que as mesmas registram, de seus contextos, assim como das implicações e relações que tenham com as formas de expressão diferenciadas, que chamamos: Arte

Full textEns trobem a l’era de la informació on la majoria de les dades s’emmagatzemen en format digital. Per tant, la gestió de documents i vídeos digitals requereix el desenvolupament de tècniques eficients per a l’anàlisi automàtic. Entre elles, la captura de la similitud o dissimilitud entre diferents imatges de documents o fotogrames de vídeo és extremadament important. En aquesta tesi, analitzem, a diverses resolucions d’imatge, el comportament de tres famílies diferents de mesures basades en similitud d’imatges i aplicades a la classificació de factures. En aquests tres conjunt de mesures, el càlcul de la similitud entre dues imatges es basa, respectivament, en les diferències d’intensitat, en la informació mútua, i en la distància de compressió normalitzada. Degut a que els millors resultats s’obtenen amb les mesures basades en la informació mútua, es procedeix a investigar l’aplicació de tres generalitzacions de la informació mútua basades en Tsallis en diferents índexs entròpics. Aquestes tres generalitzacions es deriven respectivament de la distància de Kullback-Leibler, la diferència entre l’entropia i entropia condicional, i la divergència de Jensen-Shannon. En relació al processament de vídeo digital, proposem dos enfocaments diferents de teoria de la informació basats respectivament en la informació mútua de Tsallis i en la divergència de Jensen-Tsallis, per detectar els límits d’un pla cinematogràfic en una seqüència de vídeo i per seleccionar el fotograma clau més representatiu de cada pla. Finalment, l’entropia de Shannon s’ha utilitzat habitualment per quantificar la informativitat d’una imatge. El principal inconvenient d’aquesta mesura és que no té en compte la distribució espacial dels píxels. En aquesta tesi, s’analitzen quatre mesures de teoria de la informació que superen aquesta limitació. Tres d’elles (entropy rate, excess entropy i erasure entropy) consideren la imatge com un procés estocàstic estacionari, mentre que la quarta (partitional information) es basa en un canal d’informació entre les regions d’una imatge i els intervals de l’histograma

Full textSi historiquement, les bibliothèques numériques patrimoniales furent d’abord alimentées par des images, elles profitèrent rapidement de la technologie OCR pour indexer les collections imprimées afin d’améliorer périmètre et performance du service de recherche d’information offert aux utilisateurs. Mais l’accès aux ressources iconographiques n’a pas connu les mêmes progrès et ces dernières demeurent dans l’ombre : indexation manuelle lacunaire, hétérogène et non viable à grande échelle ; silos documentaires par genre iconographique ; recherche par le contenu (CBIR, content-based image retrieval) encore peu opérationnelle sur les collections patrimoniales. Aujourd’hui, il serait pourtant possible de mieux valoriser ces ressources, en particulier en exploitant les énormes volumes d’OCR produits durant les deux dernières décennies (tant comme descripteur textuel que pour l’identification automatique des illustrations imprimées). Et ainsi mettre en valeur ces gravures, dessins, photographies, cartes, etc. pour leur valeur propre mais aussi comme point d’entrée dans les collections, en favorisant découverte et rebond de document en document, de collection à collection. Cet article décrit une approche ETL (extract-transform-load) appliquée aux images d’une bibliothèque numérique à vocation encyclopédique : identifier et extraire l’iconographie partout où elle se trouve (dans les collections image mais aussi dans les imprimés : presse, revue, monographie) ; transformer, harmoniser et enrichir ses métadonnées descriptives grâce à des techniques d’apprentissage machine – machine learning – pour la classification et l’indexation automatiques ; charger ces données dans une application web dédiée à la recherche iconographique (ou dans d’autres services de la bibliothèque). Approche qualifiée de pragmatique à double titre, puisqu’il s’agit de valoriser des ressources numériques existantes et de mettre à profit des technologies (quasiment) mâtures.

Full textThe thought of Vilém Flusser (1920-1991) has given rise to an abundant critical bibliography on his contributions in the field of communication, where his wager on a "new imagination" brings together art, science and technology, under the aegis of his philosophy of photography. The archaeology of his thought, proposed here, is constructed alongside this disciplinary underpinning of his work in the theories of communication and media: it involves the notion of art that Flusser developed during his career, in order to grasp the deployment of this artistic dimension, its status and its contours, in his thought. Flusser's notion of art is inseparably linked to history: the traumatic experience of exile becames central in his critical thinking regarding all totalitarianism. The practices and knowledge that underpin his relationship to the world and guide the development of his conception are worked on by a Kulturgeschichte, seen from the perspective of a "post-history". But there is, in particular, a playful thinking of the game, where the objective is less to play within the established rules than to thwart the rules, to "play to change the game". In other words, it is a radically dialogical and polyphonic way of thinking, whose Kommunikologie, shaped as metatheory, directs the development of Flusser's work. His historical trajectory and the knowledge associated with it contribute to the construction of a cybernetic way of thinking that sketches the fundamental lines of a Kunstwissenschaft, in which he proposes a kind of iconoclasm without giving up images

Resumo: Estrada, Paisagem e Capim - Fotografias e Relatos no Jalapão é uma pesquisa em Poética Visual constituída por viagens - como deslocamento e experiência estética - ao cerrado jalapoeiro, no interior do Estado do Tocantins. A fotografia digital e as anotações se constituem como expressão e desenvolvimento do percurso processual do trabalho realizado. As referências teóricas e visuais contaram com a Antropologia como essência, metodologia e inserção no campo de pesquisa e a Arte como espaço de reflexão e criação para o caminho poético. Diferentes questionamentos surgiram ao longo do desenvolvimento do fazer artístico e acabaram por delimitar o trabalho. Nesta pesquisa, arte, natureza e cultura tornam-se pares no processo de registro e percepção da intuição criativa fotográfica, enfatizando assim, o caráter de "work in progress". Um Livro de Fotografias e um DVD sonorizado com 170 imagens são apresentados como processo e resultado do trabalho poético
Abstract: Road, Landscape and Grass - Photographs and Reports in the Jalapão is a research in Poetic Visual consisting of travels - such as displacement and aesthetic experience - to the brazilian savannah, in the State of Tocantins/BR. The digital photography and the written summary notes are as expression and development of the proceedings of the visual work done. The theoretical and visual references counted with the Anthropology as well as essence, methodology and insertion in the field of research, and the Art to be a space for reflection and creation for the poetic way. Different questions have arisen in the course of the development of artistic making and ultimately define the work. In this research, art, nature and culture have become parts in the process of registration and perception of the creative intuition photographic, emphasizing the character of "work in progress". A book of photographs and a DVD with sound and 170 images are presented as a process and outcome of the research poetic

To do so, we have modelised the movement of the satellite and his optical system to transform the two first images in another one, epipolar which will allow us to reduce the matching time and to find with success the equivalent pixels. For the pairing, we have utilised a technic wich is based on the corrolation and of the dynamic programming. This method was very satisfactory and allow us to match 96 % of the equivalent pixels, with an error of less than 5 meters, but the original problem is still a matter of research for complimentary studing

Full textEste trabalho tem por objetivo apresentar uma nova proposta aos algoritmos de Demosaicing existentes, utilizando uma abordagem mais flexível quanto ao uso do Color filter array (CFA) em imagens coloridas de único sensor. O algoritmo proposto tem como base a estrutura de problemas inversos, cujo funcionamento utiliza um modelo de operação matriz-vetor que é adaptável ao CFA empregado. A partir deste conceito, o algoritmo trata o problema de Demosaicing como o de minimização de função custo, com um termo referente à dependência da estimativa com os dados obtidos e com o modelo de captura, o outro termo é relacionado aos conhecimentos observados em imagens que podem ser explorados para uma estimativa mais precisa, tal elemento é chamado de Prior. A proposta estabelecida tem como base algoritmos de regularização com foco na alta correlação presente entre os canais de cor (R, G e B), e na suavidade local de regiões uniformes, essa base formaliza o Prior empregado no trabalho. A minimização da proposta é atingida iterativamente através do IRLS-CG, que é a combinação de dois algoritmos de minimização eficientes, que apresenta rápidas respostas, e a capacidade de trabalhar com a norma L1 em conjunto com a norma L2. Com o intuito de atestar a qualidade do algoritmo proposto, foi elaborado um experimento em que o mesmo foi testado com diferentes CFAs e em situação com ruído gaussiano de 35dB e sem ruído algum em imagens da base de dados da Kodak, e os resultados comparados com algoritmos do estado-da-arte, no qual o desempenho da proposta apresentou resultados excelentes, inclusive em CFAs que destoam do padrão Bayer, que é o mais comumente usado na atualidade.
This research presents a new proposal to Demosaicing algorithms, using a more flexible approach to deal with the Color filter array (CFA) in single sensor color imaging. The proposed algorithm is structured in the inverse problems model, whose functions employ a CFA adaptive matrix-vector operational model. From this concept, the Demosaicing problem is treated as a cost function minimization with two terms, one referring to the dependence between the estimation and the data provided by the acquisition model, and other term related to features observed in images, which can be explored to form a more precise estimation, this last term is known as Prior. The established proposal is applied in regularization algorithms with focus on the high correlation among color channels (R, G, and B), and in the local smoothness of uniform regions. Both characteristics organize the Prior employed in this work. The minimization proposed is iteratively achieved through IRLS-CG, which is the combination of two efficient minimization algorithms, that presents quick responses, and the capacity to deal with L1 and L2 norm at the same time. The quality of the proposed algorithm is verified in an experiment in which varous CFA were used and a situation with 35dB gaussian noise and another one with no noise applied to the Kodak dataset, and the results were compared with state-of-the-art algorithms, in which the performance of the proposed Prior showed excellent results, including when the CFA is different from Bayer’s, which is the most commonly used pattern.

Full textThe present thesis proposes new methods for obtaining objective and accurate diagnoses in modern healthcare. Non-invasive techniques have been used to examine or diagnose three different medical conditions, namely neuropathy among diabetics, radiotherapy induced erythema (skin redness) among breast cancer patients and diagnoses of cutaneous malignant melanoma. The techniques used were Near-InfraRed spectroscopy (NIR), Multi Frequency Bio Impedance Analysis of whole body (MFBIA-body), Laser Doppler Imaging (LDI) and Digital Colour Photography (DCP).
The neuropathy for diabetics was studied in papers I and II. The first study was performed on diabetics and control subjects of both genders. A separation was seen between males and females and therefore the data had to be divided in order to obtain good models. NIR spectroscopy was shown to be a viable technique for measuring neuropathy once the division according to gender was made. The second study on diabetics, where MFBIA-body was added to the analysis, was performed on males exclusively. Principal component analysis showed that healthy reference subjects tend to separate from diabetics. Also, diabetics with severe neuropathy separate from persons less affected.
The preliminary study presented in paper III was performed on breast cancer patients in order to investigate if NIR, LDI and DCP were able to detect radiotherapy induced erythema. The promising results in the preliminary study motivated a new and larger study. This study, presented in papers IV and V, intended to investigate the measurement techniques further but also to examine the effect that two different skin lotions, Essex and Aloe vera have on the development of erythema. The Wilcoxon signed rank sum test showed that DCP and NIR could detect erythema, which is developed during one week of radiation treatment. LDI was able to detect erythema developed during two weeks of treatment. None of the techniques could detect any differences between the two lotions regarding the development of erythema.
The use of NIR to diagnose cutaneous malignant melanoma is presented as unpublished results in this thesis. This study gave promising but inconclusive results. NIR could be of interest for future development of instrumentation for diagnosis of skin cancer.
