Full textEn l'última dècada, les xarxes neuronals profundes han revolucionat el camp de la visió per computador. Els resultats favorables obtinguts amb arquitectures neuronals profundes entrenades per resoldre tasques de reconeixement visual han causat un canvi de paradigma cap al disseny de mètodes basats en representacions d'imatges apreses de manera automàtica, deixant enrere les tècniques tradicionals basades en l'enginyeria de representacions. Aquest canvi ha permès l'aparició de tècniques basades en l'aprenentatge d'extrem a extrem (end-to-end), capaces de resoldre de manera efectiva molts dels problemes tradicionals de la visió per computador (e.g. classificació d'imatges o detecció d'objectes), així com nous problemes emergents com la descripció textual d'imatges (image captioning). Donat el context de la ràpida evolució de la visió per computador en el qual aquesta tesi s'emmarca, presentem contribucions alineades amb tres dels canvis més importants que la visió per computador ha experimentat recentment: 1) la reutilització de representacions extretes de models neuronals pre-entrenades per a tasques auxiliars, 2) els avantatges de formular els problemes amb solucions end-to-end entrenades amb grans bases de dades, i 3) el creixent interès en utilitzar llenguatge natural en lloc de conjunts d'etiquetes categòriques pre-definits per descriure el contingut visual de les imatges, facilitant així l'extracció d'informació visual més enllà del reconeixement de l'escena i els elements que la composen La primera part de la tesi està dedicada al problema de la cerca d'imatges (image retrieval), centrada especialment en l'obtenció de representacions visuals significatives i discriminatòries que permetin la recuperació eficient i efectiva d'imatges donada una consulta formulada amb una imatge d'exemple. Les contribucions en aquesta part de la tesi inclouen la construcció de representacions Bag-of-Words a partir de descriptors locals obtinguts d'una xarxa neuronal entrenada per classificació, així com un estudi dels avantatges d'utilitzar xarxes neuronals per a detecció d'objectes entrenades utilitzant les imatges d'exemple, amb l'objectiu de millorar les capacitats discriminatòries de les representacions obtingudes. La segona part de la tesi presenta contribucions al problema de predicció de conjunts a partir d'imatges (image to set prediction), entès com la tasca de predir una col·lecció no ordenada d'elements de longitud variable donada una imatge d'entrada. En aquest context, presentem una anàlisi exhaustiva dels mètodes actuals per a la classificació multi-etiqueta d'imatges, que són capaços de resoldre la tasca de manera integral calculant simultàniament la distribució probabilística sobre etiquetes i la cardinalitat del conjunt. Seguidament, estenem l'anàlisi dels mètodes de predicció de conjunts a la segmentació d'instàncies semàntiques, presentant un model recurrent capaç de predir conjunts d'objectes (representats per màscares binàries i etiquetes categòriques) de manera seqüencial. Finalment, la tercera part de la tesi estén els coneixements apresos en les dues parts anteriors per presentar solucions d'aprenentatge profund per connectar imatges amb llenguatge natural en el context de receptes de cuina i imatges de plats cuinats. En primer lloc, proposem una solució basada en algoritmes de cerca, on la recepta escrita i la imatge es codifiquen amb representacions compactes que permeten la recuperació d'una donada l'altra. En segon lloc, com a alternativa a la solució basada en algoritmes de cerca, proposem un model generatiu capaç de predir receptes (compostes pels seus ingredients, predits com a conjunts, i instruccions) directament a partir d'imatges de menjar.

Full textEl Reconeixement Biomètric fa referència a la identi cació automàtica de persones fent us d'alguna característica o modalitat anatòmica (empremta digital) o d'alguna característica de comportament (signatura). És un aspecte fonamental en qualsevol procés relacionat amb la seguretat, la compartició de recursos o les transaccions electròniques entre d'altres. És converteix en un pas imprescindible abans de concedir l'autorització. Aquesta autorització, s'entén que protegeix recursos clau, permeten així, que aquests siguin utilitzats pels usuaris que han estat autoritzats a utilitzar-los o a tenir-hi accés. Els sistemes biomètrics poden funcionar en veri cació, on es resol la pregunta: Soc jo qui dic que soc? O en identi cació on es resol la qüestió: Qui soc jo? La comunitat cientí ca ha incrementat els seus esforços per millorar el rendiment dels sistemes biomètrics. En funció de l'aplicació, diverses solucions s'adrecen a treballar amb múltiples modalitats o combinant diferents mètodes de classi cació. Donat que incrementar el número de modalitats, representa a la vegada problemes pels usuaris, moltes d'aquestes aproximacions no arriben mai al mercat. La tesis contribueix principalment en tres grans àrees, totes elles amb el denominador comú següent: Reconeixement biometric a través de les mans. i) La primera d'elles constitueix la base de qualsevol estudi, les dades. Per poder interpretar, i establir un sistema de reconeixement biomètric prou robust amb un clar enfocament a múltiples fonts d'informació, però amb el mínim esforç per part de l'usuari es construeix aquesta Base de Dades de mans multi espectral. Les bases de dades biomètriques constitueixen un recurs molt preuat per a la recerca; sobretot si ofereixen algun element nou com es el cas. Imatges de mans en diferents espectres electromagnètics: en visible (VIS), en infraroig (NIR) i en tèrmic (TIR). Amb un total de 100 usuaris, i 10 mostres per usuari, constitueix un bon punt de partida per estudiar i posar a prova sistemes multi biomètrics enfocats a les mans. ii) El segon bloc s'adreça a les dues aproximacions existents en la literatura per a tractar les dades en brut. Aquestes dues aproximacions, anomenades Holística (tracta la imatge com un tot) i Geomètrica (utilitza càlculs geomètrics) de neixen el focus alhora d'extreure el vector de característiques. Abans de tractar alguna d'aquestes dues aproximacions, però, és necessària l'aplicació de diferents tècniques de preprocessat digital de la imatge per obtenir les regions d'interès desitjades. Diferents problemes presents a les imatges s'han hagut de solucionar de forma original per a cadascuna de les tipologies de les imatges presents: VIS, NIR i TIR. VIS: imatges sobre exposades, anells, mànigues, braçalets. NIR: Ungles pintades, distorsió en forma de soroll en les imatges TIR: Dits freds La segona àrea presenta aspectes innovadors, ja que a part de segmentar la imatge de la ma, es segmenten tots i cadascun dels dits (feature-based approach). Així aconseguim contrastar la seva capacitat de reconeixement envers la ma de forma completa. Addicionalment es presenta un conjunt de procediments geomètrics amb la idea de comparar-los amb els provinents de l'extracció holística. La tercera i última àrea contrasta el procediment de classi cació anomenat Biometric Dispersion Matcher (BDM) amb diferents situacions. La primera relacionada amb l'efectivitat respecte d'altres mètode de reconeixement, com ara l'Anàlisi Lineal Discriminant (LDA) o bé mètodes com KNN o la regressió logística. Les altres situacions que s'analitzen tenen a veure amb múltiples fonts d'informació, quan s'apliquen tècniques de normalització i/o estratègies de combinació (fusió) per millorar els resultats. Els resultats obtinguts no deixen lloc per a la confusió, i són certament prometedors en el sentit que posen a la llum la importància de combinar informació complementària per obtenir rendiments superiors.

A proposição da temática desta tese constitui-se no levantamento da discussão que trouxe à tona a possibilidade real de uma pessoa cega construir imagens mentais. Discutiu-se, pois, a viabilidade da construção dessas imagens a partir das próprias condições de que o indivíduo cego é dotado. Procurou-se demostrar como o corpo com seus sentidos e suas ilimitadas valências, converte-se em instrumental capaz de acionar recursos sensoriais que dão informações, passam dados, concretizam sensações e percepções, formulam conceitos. Sobre o tripé – conhecimento, cultura e artes –, fez-se uma pesquisa que, pela complexidade e abrangência do assunto, exigiu o cruzamento de diferentes disciplinas, de diversas linhas de pensamento, ainda que guardando diferenças pudessem estabelecer um diálogo que levasse a compreensão mais clara ao cerne da proposta feita. Recorreu-se a Zubiri, Bachelard e Durand para compor a base da leitura de três poetas cegas e da escritora Marina Colasanti, apontando a força expressiva das imagens em ambos os casos.
The proposition of the theme of this thesis is the discussion collection that highlights the real possibility of a blind person to construct mental images. The possibility of constructing these images was therefore discussed from the very conditions of which the blind individual is endowed. We sought to demonstrate how the body, with its senses and its unlimited valences, becomes an instrument capable of assessing sensory resources which give information, pass data, materialize sensations and perceptions, formulate concepts. On the tripod - knowledge, culture and the arts - a research was made that due to the complexity and comprehensiveness of the subject, required the crossing of different disciplines, of different lines of thought, even if keeping their differences it could establish a dialogue that would lead to understanding clearly the heart of the proposal. Zubiri, Bachelard and Durand were used to compose the basis of the reading of three blind poets and the writer Marina Colasanti, pointing out the expressive force of the images in both cases.

Full textSome theatrical pieces from this 21st century seem to include in their esthetical project a question of the perceptive order by creating new ways of seeing, hearing and being affected. The drama ‒ as an action ‒ finds itself updated in a form addressing to the spectator’s perceptions through visual dramaturgy, even perceptive, based on a factory of scenic images. Our study offers to invest in the theater field a part of the research and thoughts about the image by putting into perspective the esthetical, philosophical, and even political questions that the notion of scenic image raise.The particular piece from the Italian director Romeo Castellucci is representative of the visual artist’s specificity who finds on the stage a new creating support for images, a particular way of involving body, space, shape, matter and where the text, although especially mute, is haunting the stage. This plastic theater questions the foundations of traditional theater (action, character, fiction), creates a properly figural drama and tries to move the spectator’s sight. In an oscillation between visual appearance and disappearance, representation and unspeakable, he offers to the spectator an experiential process in a laboratory where image plays against image, worries the sight and the accepted perceptions of reality.The displacement of the image’s theory in the theatrical field will allow us, through Romeo Castellucci’s singular approach, to make our contribution to the operating procedures analysis of his aesthetic’s efficiency, reception mechanism of the spectator and critical and political skates of the contemporary theater

Full textAt the age of visual totalitarianism, how to show and how to see are more than ever fascinating and insolvent questions. Voracious and unpredictable video image is a very special vehicle to analyse the condition of visibity in actual arts. The restoration of visibility always requires hurting the smooth surface of the image. In video art, this function may be attribuated to its technical system as new frame for video artworks : this material agencement becomes a reflexive and critical system for aesthetics experience. In the middle of contemporary video installation’s images, we’ll try to understand the terms and issues which invent this decisive link between the eye and the image : an exploration of the darkness which sets going the luminous images’ travel

Full text"There is no image to the theater. it is the invisible which comes in the image and the unspeakable which comes in the world". Her is how Olivier Py, defines the theater, the text and the representation. The study of the image in the theater of Olivier Py is the reflection on the evolution of the contemporary dramatic text and on the process of exercise of the look of a spectator who is in the crossroads of the various traditional and modern esthetics. The migration of the image of the text in the podium raises the question which upsets all the process of the theatrical creation, as well on the theoretical plan that has a practice.The written poem is not any more only a coherent organization of accomplished actions but, also, the space where the writing allows the transport of the logos to the opsis. The scene becomes, hence, the dialectical space of the sharing of the sensitive between actor and spectator, stage and room, real and virtual, visible and invisible...Concisely, the theater of Olivier Py is the universe of the effigies which show themselves in real presence, "as in a state of grace", but which, speedly, become fleeting, figures, enactments, as spectres which get away

Full textThis work tries to contribute to the research of a complex problem: how to study image today, and how to think its sharing. To elaborate an answer to this question, the problem was situated in a discussion about the representation and put in a connection with a triple questioning - ontological, axiological and epistemological - of the sharing of the visible, which is understood as one of the problems of the contemporary political philosophy. The method, which is used, consists to analyze the statements (texts explaining the legitimately visible images) and the visibilities (images chosen as appropriate illustrations of the textes) in the field of the archive. The study of a particular case - that consists to analyze a double official mode of working with documentary photographs taken during the period of normalisation in slovakia - reveals the fact that nor during the period of the authoritative regime of normalisation, neither during the contemporary period so called democratic, the legitimate sharing of the visible is possible without fixing certain esthetic norms which function as political limits of the vision: no sharing of the being, of the values and of the knowledge by means the image is possible without intervention of speaking and without production of representations

Full textDenna studie syftade till att undersöka tillämpligheten av tre olika informationsteoretiska likhetsmått vid matchning av bilder, mutual information (MI), cross cumulative residual entropy (CCRE) och sum of conditional variances (SCV). Ett experiment genomfördes för att bedöma hur de olika likhetsmåtten påverkades i kontexten av multimodalitet, i detta fall i samband med infrarött och synligt ljus. Detta uppnåddes genom att köra simuleringar av fyra olika scenarier med hjälp av bilder tagna i infrarött och synligt ljus, och dessutom med variationer i mängden detaljer för att skapa olika experimentella uppsättningar. Nämligen experimentuppsättning A: unimodala datamängder med mer / mindre detaljer och experimentuppsättning B: multimodala datamängder med mer / mindre detaljer. Resultatet visade att multimodalitet har en statistiskt signifikant påverkan på alla likhetsmått. Observationer gjordes att likhetsmåttens beteenden, när man försöker matcha bilder med olika mängd detaljer, skilde sig från varandra. Detta gav en grund för bedömning av vilken av dessa likhetsmått som då kunde användas för att ge de mest tydliga och stabila resultaten som möjligt beroende på variationen av mängden detaljer i datat. Med denna studie drogs slutsatsen att likhetsmåttet CCRE gav mest de tydliga och stabila resultaten i samband med multimodalitet gällande infrarött och synligt ljus för båda fallen av mer eller mindre detaljer. Även om de andra likhetsmåtten också gav goda resultat i vissa fall, skulle CCRE vara att rekommendera, som observerat i denna studie.

This thesis aims at understanding and presenting the image open, phenomenological, founding in his perception, which updates its full potential embodied in the means of visibility, which culminates in the process of representation and validation of the perceived real, where the image gains strength and takes the position of mediation between man and the world, adopting the assumptions of Flusser. This work is justified when it exposes the impossibility of viewing the real, or rather, points to the invisibility of the image that simulates the real perceived, given his acknowledged inability to naturally present to the world, according to the precepts of Merleau-Ponty. We try to track one of the most prolific and problematic of philosophy and Communication Sciences, feeling the concepts and functions of the image. For this, we use two types of approaches. An anthropological (empirical), history and culture, which describes the image "artefactum," propagated by the many supporters and media at the same time, the mediator of the ways of perceiving the man in the world. An introductory way, discusses the origin, evolution and characteristics of dialectical exchange with other languages and their hunger contemporary media. Another, on the epistemological approach (theoretical), examines the essence of the image function as an interface between the possibilities of sensible and intelligible subject, present and aware of their cognitive amplitudes. The analysis of the mechanisms of representation and language, representationalist presented by the studies of art history and media, where the image takes up space as a fundamental means of existence and visibility, a wide fertile reflection, that in contrast to studies of the phenomenology of perception and the principles of contemporary semiotics are examined, mainly in the assumptions and contributions of Merleau-Ponty, Flusser, Mitchell, Baitello, Belting and Català Domènech. The hypothesis search visibility for the phenomenological status of the image, in order to legitimize the proposal for a "reading" open the image without the proper supports media in which it takes shape and becomes visible. Regardless of your need to "embodiment" to support, knowledge "theoretical" and phenomenological characteristics of their epistemological and cultural image prior to "physical" noticeable, contribute to a better understanding of media studies and art, which is intrinsically present through the visible image. The idea that perception puts us in touch with an experience that keeps an inherently vital and at the same time, a cultural and rational intention that presents itself as our point of view about the world, expands this thesis
Esta tese objetiva a percepção e apresentação da imagem aberta, fenomenológica, fundante na sua percepção, onde atualiza seu amplo potencial de visibilidade encarnado nos meios, e que culmina no processo de representação e validação do real percebido, onde a imagem ganha força e ocupa o posto de mediação entre o homem e o mundo, adotando as premissas de Flusser. Este trabalho se justifica quando expõe a impossibilidade da visualização do real, ou melhor, aponta a invisibilidade da imagem que simula o real percebido, haja vista sua reconhecida incapacidade de se apresentar naturalmente ao mundo, conforme os preceitos de Merleau-Ponty. Procuramos rastrear um dos pontos mais fecundos e problemáticos da filosofia e das Ciências da Comunicação, tateando os conceitos e funções da imagem. Para isso, utilizam-se duas formas de abordagem. Uma antropológica (empírica), histórica e cultural, que descreve a imagem artefactum , propagada pelos inúmeros suportes midiáticos e ao mesmo tempo, mediadora das formas de percepção do homem no mundo. De forma introdutória, aborda a origem, evolução e características do intercâmbio dialético com outras linguagens e sua voracidade midiática contemporânea. Outra, na abordagem epistemológica (teórica), examina a essência, função da imagem como interface entre as possibilidades do sensível e inteligível do sujeito, presente e consciente de suas amplitudes cognitivas. A análise dos mecanismos da representação e da linguagem, apresentada pelos estudos representacionistas da história da arte e da mídia, onde a imagem ocupa espaço fundamental como meio de visibilidade e existência, fecunda uma ampla reflexão, que em contraposição aos estudos da fenomenologia da percepção e aos princípios da semiótica contemporânea são examinadas, principalmente, nos pressupostos e colaborações de Merleau-Ponty, Flusser, Mitchell, Baitello, Belting e Català Domènech. A hipótese busca a visibilidade para o estatuto fenomenológico da imagem, com a finalidade de legitimar a proposta de uma leitura aberta da imagem sem os devidos suportes midiáticos na qual ela ganha forma e se torna visível. Independentemente de sua necessidade de encarnação ao suporte, o conhecimento teórico e epistemológico de suas características fenomenológicas e culturais, que antecedem a imagem física percebível, colabora para uma melhor compreensão dos estudos da mídia e da arte, que intrinsicamente se apresentam por meio da imagem visível. A ideia de que a percepção nos coloca em contato com uma experiência que guarda uma inerência vital e, ao mesmo tempo, uma intenção cultural e racional que se apresenta como nosso ponto de vista sobre o mundo, amplia esta tese
Bonardi, Fabien. "Localisation visuelle multimodale visible/infrarouge pour la navigation autonome." Thesis, Normandie, 2017. http://www.theses.fr/2017NORMR028/document.
Full textAutonomous navigation field gathers the set of algorithms which automate the moves of a mobile robot. The case study of this thesis focuses on the outdoor localisation issue with additionnal constraints : the use of visual sensors only with variable specifications (geometry, modality, etc) and long-term apparence changes of the surrounding environment. Both types of constraints are still rarely studied in the state of the art. Our main contribution concerns the description and compression steps of the data extracted from images. We developped a method called PHROG which represents data as a visual-words histogram. Obtained results on several images datasets show an improvment of the scenes recognition performance compared to methods from the state of the art. In a context of navigation, acquired images are sequential such that we can envision a filtering method to avoid faulty localisation estimation. Two probabilistic filtering approaches are proposed : a first one defines a simple movement model with a histograms filter and a second one sets up a more complex model using visual odometry and a particules filter
Plangger, Stefanie. "Gott im Bild : Eidôlon : Studien zur Herkunft und Verwendung des Septuagintabegriffes für das Götterbild." Thesis, Strasbourg, 2018. http://www.theses.fr/2018STRAK017.
Full textThe concept “idol” derives from ancient Greek, which is still used today. Nowadays, an Idol designates first and foremost the cult of personality but the traces of the ancient meaning are partly preserved. The term idol focuses on the veneration of foreign deities and their pictorial representations. Therefore, idols contrast with the monotheism and an iconism of the god of Israel. This study elaborates the original meaning of the Greek word eidôlon which becomes the standard expression for divine images since its usage in the Septuagint and afterwards. It seems that there did not exist a major term for cult images in the Greek culture. The comparison and the exact analysis of the Hebrew and Greek equivalents form the major part of the thesis. In the case of eidôlon there does not exist a Hebrew standard equivalent but a variety of Hebrew lexemes which are all translated by the Greek word in the Septuagint. In general, eidôlon appears in important and authoritative texts (Exodus 20: the Second Commandment,Deuteronomy 32: The Song of Moses). Concerning the choice of terminology, eidôlon is astrategic and theological move of the translators because this Greek expression includes allmajor characteristics of foreign deities. A clear distinction between JHWH the god of Israel andall other deities becomes clear

Full textHow can Milton’s poet claim that he intends to «see and tell / Of things invisible to mortal eyes » (III, 54-55) or that he is going to disclose the « invisible exploits » (V, 565) of the angels in the epic? The aim of this study is to show that Milton’s project to make invisible things visible, is profoundly original in both aesthetic and theological terms. His argument is rooted in a theology of his own which he acknowledges to be heretical. By rejecting the Calvinist idea of predestination, preferring instead the doctrine of Arminius, Milton forges a poetic persona who is granted a specific and superior illumination. Moreover, Milton refutes the dogma of the Trinity, and conceives the Son as the first created image of the invisible Father. Such a conception of the Son provides him with a model for his poetics of the invisible. Finally, Milton's poetics is based on a definition of scriptural accommodation which is in opposition to the Augustinian definition usually adopted by the Protestants. To give coherence to his project Milton elaborates an epic poetics which is centred on the figures of the poet and the Son and whose final aim is the representation of the invisible. To make the invisible glory of God visible, he introduces a hierarchy of images and words concerning the manifestations of light which parallels the hierarchy of living things in the universe. The second aspect of Milton’s visual aesthetics concerns a fragmenting of unified sight and its subsequent reconstruction by the omniscient narrator

Full textThis study is about the analysis of the coexistence of reality and imagination in the work of Apichatpong Weerasethakul. The modalities of encountering and crossing of these two dimensions in a film or between films are clarified through practical and detailed observations. On the basis of an analysis of the influence of two different cultures – the Thai indigenous sensibility and the tendency of Western experimental cinema –, we search on the one hand the modalities of capturing the scenes of real life, and on the other hand how to discover and reveal the invisible side that surrounds this visible field. The narrative of his films is represented in a diverse way by deviating from the classical rule. In the process of forming a narrative, heterogeneous materials are embraced and various texts are connected. Moreover, the flexible and free world of Weerasethakul always presupposes virtual multiple times, an essential characteristic that can be found in all his works, from short films to installations to the feature films. Therefore, the distinction between the real dimension and the unreal / surreal dimension loses clarity; the line of distinction is virtually canceled. The filmmaker thus proposes another view of the world based on the Thai Buddhist tradition that might seem absurd from the point of view of modern rationalism of the West. By crossing the discussions around the hybrid world of Weerasethakul, this study aims to demonstrate that his cinema (re)finds the beauty and power of reality through the imagination

Full textAlong this work, we have used the potentiality of different modalities of imagery that we apply to the plant domain so as to contribute to the high-throughput phenotyping of seeds and seedlings. We have mainly committed ourselves to the search for answers to two specific and important problematic in this domain. We begin by showing the applicability of visible imaging using an inactinic light and passive thermographic imaging to image the development of seeds and seedlings, a biological phenomenon usually occurring in soil and darkness. We present our contributions to this type of imaging through our contributions to the conception and the realization of a vision system using visible inactinic imaging, whose finality is the realization of individualized automated measurement on the seeds, the seedlings and the organs of the seedlings. This system handle seedling crossing, through the original use of anisotropic diffusion, which allowed us to multiply, without information loss, the output by ten. Furthermore, this system carries out the separation of the organs by means of a generic criterion based on gravitropism. The validation of the image processing algorithms of the vision system use original ways (numerical simulation and test of the influence of the uncertainty through agronomic simulation). Thermographic imaging, which captures the passive heat radiation of objects, allows us to visualize and to measure seeds and seedlings in the darkness. It also allows realizing the segmentation and the tracking of the organs of seedlings. This imaging technology also allowed us to demonstrate the feasibility of a non-destructive determination of sugar quantity in organs of beet seedlings. We then propose a generic methodology that allows the conception of spectrally optimized low-cost sensors, according to determined application tasks. This methodology uses information theory, to extract from, relatively expensive, hyperspectral imaging, the information needed for the conception of the dedicated low-cost sensors. The interest of this methodology for plant phenotyping has been shown and justifies its transfer to the world of research in plant biology

Full textNew generation of imaging spectrometers are emerging in the field of space exploration by adding an additional view of measurement, the angular dimension. Multi-angle imaging spectroscopy is conceived to provide a more accurate characterization of planetary materials and a higher success in separating the signals coming from the atmosphere and the surface. The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) aboard the Mars Reconnaissance Orbiter is a hyperspectral camera that operates systematically in multi-angle mode from space. Nonetheless, multi-angle hyperspectral images are related to problems of manipulation, visualization and analysis because of their size and complexity. In this framework, this PhD thesis proposes robust statistical and physical algorithms to analyze images acquired by the CRISM instrument in an efficient manner. First, I propose a tailor-made data pipeline aimed at improving the radiometric quality of CRISM data and generating advanced products, the latter data being devised to perform fine analysis of the planet Mars. Second, I address the atmospheric correction of CRISM imagery by exploiting the multi-angle capabilities of this instrument. An innovative physically-based algorithm compensating for atmospheric effects is put forward in order to retrieve surface reflectance. This approach is particularly used in this thesis to infer the photometric properties of the materials coexisting in a specific site of Mars, the Gusev crater. Third, I perform an intercomparison of a selection of state-of-the-art techniques aimed at performing spectral unmixing of hyperspectral data acquired by the CRISM instrument. These statistical techniques are proved to be useful when analyzing hyperspectral images in an unsupervised manner, that is, without any a priori on the scene. An original strategy is proposed to discriminate the most suitable techniques for the exploration of Mars based on ground truth data built from independent high resolution imagery

This thesis describes how the fusion of visible and thermal infrared (IR) images can be used to improve the performance of face recognition techniques, especially when illumination variations and occlusions are involved. Visible images are sensitive to illumination variations, while thermal IR images are robust to them. However, thermal IR images are degraded by occlusions caused from eyeglasses, but visible images can provide detailed information around the eyes even when eyeglasses are present. Fusion techniques, which combine complementary information from both spectrums, generate information that is robust to both illumination variations and occlusions. Before two images are fused, they must be registered. In this thesis, edge-based mutual information is used to register both visible and thermal IR images taken under different conditions. Following that, eyeglasses (if present) are removed from the thermal IR image, and replaced by eyes that are reconstructed from the visible image. Then, data-level, feature-level, and score-level fusion techniques are applied to the visible and thermal IR images for face recognition. Experimental results using the NIST/Equinox database showed that the fusion of visible and thermal IR images increased the number of first matches by 22% over visible images, and 8% over thermal IR images. Unfortunately, thermal IR sensors may be cost-prohibitive for many applications. In consideration of this, this thesis explores ways to predict a novelty component from the visible image. A novelty component is a thermal-like image that can be obtained from information in the visible image. It is later fused with the visible image for face recognition. Experimental results based upon four face recognition algorithms showed that the fusion of visible images and their novelty components increased the number of first matches over visible images by 21% (using the NIST/Equinox database) and 17% (using the Extended Yale Face Database B).

Revelando uma cumplicidade inesperada, o cinema submerge nos ritmos da cidade, tornando—os visíveis. Ä cidade como cenário mutável, de estratos cumulativos de memórias e vestígios materiais dos gestos, dos tempos que a vão construindo. O cinema descobre esse território de utopias e apropria—se dos seus desejos materializando—os no suporte fugaz das imagens, do falso movimento que projecta a realidade num devir. Através da análise de filmografia, estabeleceram—se paralelismos com a cidade Moderna; assumindo uma relação simbiótica com as dinâmicas da cidade, o olho da câmara é comovido pelo impacto dessa realidade, restituindo, num espaço ilusório, a sua ordem invisível. Um espaço urbano que flutua por um mundo de imagens imateriais, espaço fictício e tecnificado. Habitamos num cenário fixo embora procuremos um espaço fugaz, em trânsito. A arquitectura vive aprisionada entre a imagem e a sua materialidade, entre a ilusão e a realidade. Entre a ideia e o "desejo de ser da forma". É nesse espaço heterotópico entre o sonho e a realidade que o cinema opera construindo num espaço verossímil a cidade impossível.
ABSTRACT: With this work we intend to make a link between two disciplines: architecture and cinema. Revealing an unexpected complicity, cinema sinks into the city rhythms, making them visible. The city as a mutable organism of superimposed memory s tracts, material traces of gestures, comprising the time which gave form to it. Cinema finds that land of utopias, sharing and appropriating its desires, material rising them on his own fugacious image support, of the false raccord that projects actual reality into a possible future. Trough analysis of filmography, establishing a parallel between cinema and Modern city, this work assumes the existence of a symbiotic relationship linking the city dynamics and the camera eye impressed by reality, bringing back, on an illusory space, its hidden order. An urban space that float over a world of immaterial images, technified and fictitious. We live on a settle scenery although we search a fugacious one, in transit. Architecture lives imprisoned between image and its own materiality. Between reality and illusion. Between the idea and the "desire to be" of form. In a heterotopic space, between dream and reality, the cinema builds in a likely space the impossible city.

Full textAlmost everyone carries a high-quality camera in their smartphone and uses it to communicate with other individuals and for the last two decades, people are increasingly making use of images and videos in their transportable communication. As the prices of the storage are decreasing, the number of photos stored is increasing, leading to collections of images whose sizes begin to be a barrier for relieving the captured moments and exploring them. We are submerged by images. In order to ease the problem of oversized image collections, methods that aim to select a subset of photos that best represents them have been designed and proposed in the literature. Those methods typically rely upon the prediction of perceptual features such as, for example, the image quality, aesthetics, and memorability, to select the best images. This thesis starts from the fundamental image properties that guide the image selection, respectively the image quality and image aesthetics. First, the perceived image quality assessment is investigated in an anomaly detection manner, contrary to the most common regression task. This is because rather than predict a score that best correlates to the average human opinion, being able to distinguish good quality images from bad ones, is more suitable for the image collection management problem, furthermore, it requires fewer images to tune the model. Then the problem of automatic assessment of image aesthetics is introduced. In the beginning, presenting a method that learns the aesthetics of a picture on the basis of the prediction of aesthetics-related attributes. Then, a new solution that takes into account the semantic content, the artistic style, and the composition of the image is presented. One of the reasons people take photos is to capture important situations to recall them later on, usually with the intention of afterwards sharing their photos with other people like friends or family members. Photos can be seen as a concrete link between our memories and experienced events. Image memorability can be helpful in the organization of the selected images to better bind the memory of experienced events and the taken images. To this end in this thesis, a method for the estimation of still image memorability is presented. In particular, the proposed method goes in the direction of breaking down the intrinsic image properties that influence the memorability of the pictures. Image collections tend to have several similar images. This is because to ensure the best shot, people usually take a series of photos of the same scene. To guarantee a diverse and representative selection of images from a large collection, this thesis concludes by proposing a flexible and innovative framework that can be used to both explore large-scale image datasets and to summarize photo albums. The proposed method is designed to exploit different aspects of the images, such as the scene category, image quality, and image aesthetics.

Full textFace recognition systems based on ’conventional’ images have reached a significant level of maturity with some practical successes. However, their performance may degrade under poor and/or changing illumination. Multispectral imagery represents a viable alternative to conventional imaging in the search for a robust and practical identification system. Multi- spectral imaging (MI) can be defined as a ’collection of several monochrome images of the same scene, each of them taken with additional receptors sensitive to other frequencies of the visible light or to frequencies beyond the visible light like the infrared region of electro- magnetic continuum. Each image is referred to as a band or a channel. However, one weakness of MI is that they may significantly increase the system processing time because of the huge quantity of data to be mined; in some cases, hundreds of MI are taken for each subject. In this thesis, we propose to solve this problem by developing new approaches to select the set of best visible spectral bands for face matching. For this purpose, the problem of best spectral bands selection is formulated as an optimization problem where spectral bands are constrained to maximize the recognition accuracy under challenging imaging conditions. We reduce the redundancy of both spectral and spatial information without losing valuable details needed for the object recognition, discrimination and classification. We have investigated several mathematic and optimization tools widely used in the field of image processing. One of the approaches we have proposed formulated the problem of best spectral bands selection as a pursuit problem where weights of importance were affected to each spectral band and the vector of all weights was constrained to be sparse with most of its elements are zeros. In another work, we have assigned to each spectral band a linear discriminant analysis (LDA) based weak classifier. Then, all weak classifiers were boosted together using an Adaboost process. From this later, each weak classifier obtained a weight that characterizes its importance and hence the quality of the corresponding spectral band. Several other techniques were also used for best spectral bands selection including but not limited to mixture of Gaussian based modeling, multilinear sparse decomposition, image quality factors, local descriptors like SURF and HGPP, likelihood ratio and so on. These different techniques enabled to build systems for best spectral bands selection that are either static with the same bands are selected for all the subjects or dynamic with each new subject get its own set of best bands. This latter category, dynamic systems, is an original component of our work that, to the best of our knowledge, has not been proposed before; all existing systems are only static. Finally, the proposed algorithms were compared to state-of-the-art algorithms developed for face recognition purposes in general and specifically for best spectral bands selection
