This process is an important step for many modern applica-tions such as Check Clearance, Optical Character Recognition and Handwriting Recognition. Improvements in the automatic process of image binarization represent impacts on applications that rely on this step. The present work proposes a methodology for automatic image binariza-tion. This methodology applies supervised learning algorithms to binarize images and consists of the following steps: images database construction; extraction of the region of interest; pat-terns matrix construction; pattern labelling; database sampling; and classifier training. Experi-mental results are presented using a database of Brazilian bank check images and the competi-tion database DIBCO 2009. In conclusion, the proposal demonstrated to be superior to some of its competitors in terms of accuracy and F-Measure. / O processo de binarização de imagens consiste na transformação de uma imagem colorida em uma nova imagem com apenas duas cores: uma que representa o fundo, outra o objeto de interesse. Este processo é uma importante etapa de diversas aplicações modernas, como a Compensação de Cheque, o Reconhecimento Ótico de Caracteres (do inglês Optical Characterer Recognition) e o Reconhecimento de Texto Manuscrito (do inglês Handwritten Recognition, HWR). Dado que melhorias no processo automático de binarização de imagens representam impactos diretos nas aplicações que dependem desta etapa o presente trabalho propõe uma metodologia para realizar a binarização automática de imagens. A proposta realiza a binarização de forma automática baseado no uso de algoritmos de aprendizagem supervisionada, tais como redes neurais artificiais e árvore de decisão. O processo como um todo consiste das seguintes etapas: construção do banco de imagens; extração da região de interesse; construção da matriz de padrões; rotulação dos padrões; amostragem da base; e treinamento do classificador. Resultados experimentais são apresentados utilizando uma base de imagens de cheques de bancos brasileiros (CMC-7 e montante de cortesia) e a base de imagens da competição DIBCO 2009. Em conclusão, a metodologia proposta apresentou-se competitiva aos métodos da literatura destacando-se em aplicações onde o processamento de imagens está restrito a uma categoria de imagens, como é o caso das imagens de cheques de bancos brasileiros. A presente metodologia apresenta resultados experimentais entre as três primeiras posições e melhores resultados em relação a medida F-Measure quando comparada com as demais.

Cette thèse a pour cadre les transmissions sur les réseaux CPL-BE et les réseaux de capteurs à faible capacité. L'état de l'art classique sur la protection de l'information dans la transmission par réseaux de capteurs fait référence à l'utilisation de codage distribué où les relais implémentent des opérations de parité (mélange des flux) sur les data issues des capteurs. Cependant, il est difficile, de par la nature variable de la qualité des liens en liaisons sans fil, de contrôler la qualité du codeur équivalent construit et de maintenir ses performances au cours du temps. C'est pourquoi nous nous sommes orientés dans cette thèse vers la recherche de schémas de codage différents qui résistent mieux à la variation de qualité des liaisons à travers le réseau. Notre choix s'est porté sur le codage par sous-espace inspiré des travaux de Gabidulin. Le but est de former un code qui utilise une métrique simple et résistante pour sécuriser les transmissions sur le réseau. Les codes à métrique de rang répondent bien à ce besoin car il n'y a qu'à contrôler le rang de la matrice obtenue en réception pour vérifier l'intégrité de la transmission. Les codes à métrique de rang et leur algorithme de décodage ont été étudiés dans un premier temps. Puis, les performances du code LRPC proposé concaténé avec les codes convolutifs sont testées dans des schémas de transmission des contextes différents. / This thesis considers the context of transmissions on CPL-BE networks and low-capacity sensor networks. The state of the art on information protection intransmission by sensor networks refers to the use of distributed coding, where therelays implement parity operations (mixing of streams) on data transmitted by thesensors. However, due to the varying nature of the quality of the wireless links, it is difficult to control the quality of the equivalent encoder constructed and to maintain its performance over time. Therefore, in this thesis, we have focused on the search for different coding schemes that are better resist the variation in the quality of the links across the network. Our choice was based on the sub-space coding inspired by Gabidulin's work. The goal is to form a code that uses a simple and resistant metric to secure transmission across the network. Rank metric codes respond well to this need because it only has to control the rank of the matrix obtained in reception to verify the integrity of the transmission. The rank metric codes and their decoding algorithm were studied in a first step. Then, the performance of the proposed LRPC code concatenated with the convolutional codes is tested in transmission schemes of different contexts.

En 1958, la Cinquième République construit ses équilibres institutionnel et fonctionnel en réaction aux dysfonctionnements des Républiques précédentes. Partie à la découverte de la majorité, elle va d’abord rejeter la valeur positive que constitue, pour la démocratie, le conflit politique. Avec l’apparition du fait majoritaire en 1962, la majorité va muer d’une logique arithmétique vers une logique institutionnelle pour devenir une structure de décision homogène dévouée au Gouvernement. La réflexion sur l’équilibre des pouvoirs va alors se renouveler. Alors que la théorie dite moderne de la séparation des pouvoirs propose de faire du contrôle de l’action du Gouvernement par l’opposition, le critère de la démocratie moderne, nous proposons une analyse différente : l’équilibre des pouvoirs repose sur la fonction de contradiction exercée par les minorités parlementaires. Cette fonction de contre pouvoir combine alors une dimension négative de limite du pouvoir, la fonction d’opposition, et une dimension positive de valeur ajoutée de la décision politique, la fonction de complémentarité législative. La thèse propose ainsi un renouvellement de la réflexion sur le processus de prise de décision dans une démocratie pluraliste. / The Fifth Republic in 1958 built its institutional and functional equilibriums in reaction to the previous Republics. It first rejected the positive value that is conflict for a democracy. With the emergence of the “fait majoritaire” in 1962, the majority evolved from a quantitative notion to an institutional notion. It became a structure of homogenous decision making devoted to the Government. Thought on the balance of powers was then renewed. While the so-called modern theory of separation of powers suggests that the criterion for a modern democracy is the check on Government action by the opposition, we propose a different analysis: the balance of powers lies in the function of contradiction assumed by the parliamentary minorities. This role of counter-power combines a negative dimension of limitation of power, the opposition function, and a positive dimension of added value to political decision making, the legislative complementary function. This thesis offers a new perspective on the decision making process in a pluralist democracy.

Digital technology has made complex signal processing possible in communication systems and greatly improved the performance and quality of most modern telecommunication systems. The telecommunication industry and specifically mobile wireless telephone and computer networks have shown phenomenal growth in both the number of subscribers and emerging services, resulting in rapid consumption of common resources of which the electromagnetic spectrum is the most important. Technological advances and research in digital communication are necessary to satisfy the growing demand, to fuel the demand and to exploit all the possibilities and business opportunities. Efficient management and distribution of resources facilitated by state-of-the-art algorithms are indispensable in modern communication networks. The challenge in communication system design is to construct a system that can accurately reproduce the transmitted source message at the receiver. The channel connecting the transmitter and receiver introduces detrimental effects and limits the reliability and speed of information transfer between the source and destination. Typical channel effects encountered in mobile wireless communication systems include path loss between the transmitter and receiver, noise caused by the environment and electronics in the system, and fading caused by multiple paths and movement in the communication channel. In multiple access systems, different users cause interference in each other’s signals and adversely affect the system performance. To ensure reliable communication, methods to overcome channel effects must be devised and implemented in the system. Techniques used to improve system performance and capacity include temporal, frequency, polarisation and spatial diversity. This dissertation is concerned mainly with temporal or time diversity. Channel coding is a temporal diversity scheme and aims to improve the system error performance by adding structured redundancy to the transmitted message. The receiver exploits the redundancy to infer with greater accuracy which message was transmitted, compared with uncoded systems. Sparse graph codes are channel codes represented as sparse probabilistic graphical models which originated in artificial intelligence theory. These channel codes are described as factor graph structures with bit nodes, representing the transmitted codeword bits, and bit-constrained or check nodes. Each constraint involves only a small number of code bits, resulting in a sparse factor graph with far fewer connections between bit and check nodes than the maximum number of possible connections. Sparse graph codes are iteratively decoded using message passing or belief propagation algorithms. Three classes of iteratively decodable channel codes are considered in this study, including low-density parity-check (LDPC), Turbo and repeat-accumulate (RA) codes. The modulation platform presented in this dissertation is a spectrally efficient wideband system employing orthogonal complex spreading sequences (CSSs) to spread information sequences over a wider frequency band in multiple modulation dimensions. Special features of these spreading sequences include their constant envelopes and power output, providing communication range or device battery life advantages. This study shows that multiple layer modulation (MLM) can be used to transmit parallel data streams with improved spectral efficiency compared with single-layer modulation, providing data throughput rates proportional to the number of modulation layers at performances equivalent to single-layer modulation. Alternatively, multiple modulation layers can be used to transmit coded information to achieve improved error performance at throughput rates equivalent to a single layer system / Dissertation (MEng (Electronic Engineering))--University of Pretoria, 2007. / Electrical, Electronic and Computer Engineering / unrestricted
