Pełny tekst źródłaThe main aim of this thesis is to investigate the automatic quality assessment of spoken language translation (SLT), called Confidence Estimation (CE) for SLT. Due to several factors, SLT output having unsatisfactory quality might cause various issues for the target users. Therefore, it is useful to know how we are confident in the tokens of the hypothesis. Our first contribution of this thesis is a toolkit LIG-WCE which is a customizable, flexible framework and portable platform for Word-level Confidence Estimation (WCE) of SLT.WCE for SLT is a relatively new task defined and formalized as a sequence labelling problem where each word in the SLT hypothesis is tagged as good or bad accordingto a large feature set. We propose several word confidence estimators (WCE) based on our automatic evaluation of transcription (ASR) quality, translation (MT) quality,or both (combined/joint ASR+MT). This research work is possible because we built a specific corpus, which contains 6.7k utterances for which a quintuplet containing: ASRoutput, verbatim transcript, text translation, speech translation and post-edition of the translation is built. The conclusion of our multiple experiments using joint ASR and MT features for WCE is that MT features remain the most influent while ASR features can bring interesting complementary information.As another contribution, we propose two methods to disentangle ASR errors and MT errors, where each word in the SLT hypothesis is tagged as good, asr_error or mt_error.We thus explore the contributions of WCE for SLT in finding out the source of SLT errors.Furthermore, we propose a simple extension of WER metric in order to penalize differently substitution errors according to their context using word embeddings. For instance, the proposed metric should catch near matches (mainly morphological variants) and penalize less this kind of error which has a more limited impact on translation performance. Our experiments show that the correlation of the new proposed metric with SLT performance is better than the one of WER. Oracle experiments are also conducted and show the ability of our metric to find better hypotheses (to be translated) in the ASR N-best. Finally, a preliminary experiment where ASR tuning is based on our new metric shows encouraging results.To conclude, we have proposed several prominent strategies for CE of SLT that could have a positive impact on several applications for SLT. Robust quality estimators for SLT can be used for re-scoring speech translation graphs or for providing feedback to the user in interactive speech translation or computer-assisted speech-to-text scenarios.Keywords: Quality estimation, Word confidence estimation (WCE), Spoken Language Translation (SLT), Joint Features, Feature Selection

Objective image quality measures play an important role in various image processing applications. In this paper quality measures applied on halftoned images are aimed to be in focus. Digital halftoning is the process of generating a pattern of binary pixels that create the illusion of a continuous- tone image. Algorithms built on this technique produce results of very different quality and characteristics. To evaluate and improve their performance, it is important to have robust and reliable image quality measures. This literature survey is to give a general description in digital halftoning and halftone image quality methods.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES).
Na última década, diversas aplicações multimídia tem gerado e distribuído conteúdos de imagens e vídeos digitais. Serviços de multimídia que tem ganhado um vasto interesse incluem televisão digital, jogos de vídeo e aplicações em tempo real operando sobre a Internet. De acordo com predições da CiscoTM, a percentagem do tráfego de dados de vídeo sobre a Internet era de 53% em 2014 e superará os 67% em 2018. Devido à esse aumento na demanda de conteúdo de dados visuais, a necessidade de métodos e ferramentas que estimem a qualidade da experiência (QoE) do consumidor é enorme. Entre os aspectos que contribuem para a QoE, a qualidade dos estímulos visuais é uma das maiores propriedades, pois pode ser alterada em diversos estágios da cadeia de comunicação, tal como na captura, na transmissão, ou na reprodução do conteúdo. Considerando que os avaliadores naturais da qualidade visual são seres humanos, a estratégia básica para medir a qualidade visual consiste na realização de experimentos subjetivos. Esses experimentos são geralmente realizados com participantes humanos em laboratórios preparados com um ambiente controlado. Esses participantes avaliam a qualidade de um dado estimulo visual (imagem ou vídeo) e atribuem a eles um valor numérico associado à qualidade. Para avaliar a qualidade, os participantes seguem um conjunto de passos experimentais. Geralmente, esses passos são padronizados para favorecer a reprodutibilidade experimental. Os padrões de experimentos incluem metodologias de avaliação, tais como condições de visualização, escala de avaliação, materiais, etc. Após um conjunto de participantes avaliarem individualmente a qualidade de um dado estímulo, a média dos valores é calculada para gerar o valor médio das opiniões subjetivas (MOS). O MOS é frequentemente utilizado para representar a qualidade geral de um dado estímulo visual. Como a coleta dos MOS é realizada a partir de experimentos com seres humanos, esse processo é demorado, cansativo, caro, e laborioso. Devido ao custo dos experimentos subjetivos, um grande esforço tem sido dedicado ao desenvolvimento de técnicas objetivas para a avaliação de estímulos visuais. Essas técnicas objetivas consistem em predizer o MOS automaticamente por meio de algoritmos computacionais. Tal automação torna possível a implementação de procedimentos computacionais rápidos e baratos para monitorar e controlar a qualidade de estímulos visuais. As técnicas objetivas para a avaliação de estímulos visuais podem ser classificadas em três tipos, dependendo da quantidade de informação necessária pelo método. Se todo o estímulo de referência (original) é requerido para a estimação da qualidade do estímulo testado, então essa técnica é classificada como sendo de referência completa. Quando somente alguma informação parcial da referência é necessária, a técnica é classificada como sendo de referência reduzida. Por outro lado, quando nenhuma informação sobre o estímulo de referência é necessária, a técnica é dita como sendo sem referência. Uma vez que a exigência de uma referência completa ou parcial é um obstáculo no desenvolvimento de diversas aplicações multimídia, as técnicas de sem referência são as mais convenientes na maioria dos casos. Diversas técnicas objetivas para avaliação de qualidade visual têm sido propostas, embora ainda existam algumas questões em aberto no seu desenvolvimento. No caso de técnicas de avaliação de imagens, diversas técnicas de referência completa têm sido produzidas com uma excelente performance. Por outro lado, técnicas que não utilizam referências ainda apresentam limitações quando múltiplas distorções estão presentes. Além disso, as técnicas sem referência para imagens mais eficientes ainda apresentam modelos computacionalmente custosos, o que limita a utilização desses métodos em várias aplicações multimídia. No caso de vídeos, o atual estado da arte ainda possui performance na predição dos MOS pior do que os métodos de imagens. Quando consideramos a acurácia da predição, os métodos objetivos para vídeos possuem uma correlação entre valores preditos e MOS ainda pequena se comparada com a correlação observada em métodos para imagens. Além disso, a complexidade computacional é ainda mais crítica no caso de vídeos, uma vez que a quantidade de informação processada é muito maior do que aquela presente em imagens. O desenvolvimento de uma técnica objetiva de avaliação de qualidade visual requer resolver três grandes problemas. O primeiro problema é determinar um conjunto de características que sejam relevantes na descrição da qualidade visual. Essas características, geralmente, referem-se às medidas de estímulos físicos, tais como quantificação da nitidez de borda, estatísticas de cenas naturais, estatísticas no domínio de curvlets, filtros de Prewitt, etc. Além disso, múltiplos tipos de características podem ser combinados para gerar um vetor de características que descrevem melhor a qualidade de um dado estímulo. O segundo problema é estabelecer uma estratégia de agrupamento das características de forma que os valores numéricos sejam descritivos dentro de um modelo. Esse agrupamento se refere a uma combinação de medidas através de um subespaço de medidas para representar o estímulo analisado. Finalmente, o terceiro problema é a criação de um modelo que mapeie as características agrupadas de forma que se correlacione com os dados preditos com os subjetivos. Neste trabalho, nós apresentamos uma investigação de métodos de avaliação de qualidade visual baseada na medição de texturas. A pressuposição é que degradações visuais alteram as texturas e as estatísticas dessas texturas em imagens e vídeos. Essas medidas são executadas em termos das estatísticas extraídas do operador de padrões binários locais (LBP) e suas extensões. Este operador foi escolhido porque ele unifica outros modelos de análise de texturas mais tradicionais, tais como o espectro de textura, o nível de cinza de comprimento (GLRLM) e as matrizes de co-ocorrência de níveis de cinza (GLCM). O operador LBP, sendo um algoritmo simples e que favorece implementações rápidas, possui propriedades muito úteis para sistemas de processamento em tempo real de imagens e vídeos. Devido às vantagens supracitadas, nós analisamos o operador LBP e algumas das suas extensões no estado da arte com o objetivo de investigar sua adequabilidade para o problema de avaliação de qualidade de imagens. Para isso, neste trabalho nós apresentamos uma extensa revisão do estado da arte dos operadores. Entre os operadores no estado da arte, podemos mencionar os padrões ternários locais (LTP), a quantização de fase local (LPQ), as estatísticas binarizadas de características de imagem (BSIF), os padrões locais binários rotacionados (RLBP), os padrões binários locais completos (CLBP), os padrões de configuração locais (LCP), entre outros. Ademais, nós também propomos novas extensões que melhoram a predição de qualidade. Entre as extensões propostas para a medida de características de qualidade, estão os padrões binários locais de múltipla escala (MLBP), os padrões ternários locais de múltipla escala (MLTP), os padrões de variância local (LVP), os padrões de planos ortogonais de cores (OCPP), os padrões binários locais salientes (SLBP) e os padrões binários locais salientes de múltipla escala (MSLBP). Para testar a adequabilidade dos operadores de texturas supracitados, propomos um arcabouço para utilizar esses operadores na produção de novas métricas de qualidade de imagens. Dessa forma, muitas métricas sem referência podem ser geradas a partir da estratégia proposta. Utilizando as métricas geradas a partir do arcabouço proposto, uma extensa análise comparativa é apresentada neste trabalho. Essa análise foi feita com três das mais populares bases de dados de qualidade imagens disponíveis, sendo elas a LIVE, CSIQ e TID 2013. Os resultados gerados a partir dos testes nessas bases demonstram que os operadores no estado da arte mais adequados para mensurar a qualidade de imagens são o BSIF, o LPQ e o CLBP. Todavia, os resultados também indicaram que os operadores propostos atingiram resultados ainda mais promissores, com as abordagens baseadas em múltiplas escalas apresentando os melhores desempenhos entre todas variações testadas. Inspirado nos resultados experimentais das métricas de imagens geradas, nós escolhemos um operador de textura conveniente para implementar uma métrica de avaliação de qualidade de vídeos. Além de incorporar informações de textura, nós também incorporamos informações de atividade espacial e informação temporal. Os resultados experimentais obtidos indicam que a métrica proposta tem uma performance consideravelmente superior quando testada em diversas bases de dados de vídeo de referência e supera os atuais modelos de qualidade vídeo.
In the last decade, many visual quality models have been proposed. However, there are some open questions involving the assessment of image and video quality. In the case of images, most of the proposed methods are very complex and require a reference content to estimate the quality, limiting their use in several multimedia application. For videos, the current state-of-the-art methods still perform worse than images in terms of prediction accuracy. In this work, we present an investigation of visual quality assessment methods based on texture measurements. The premise is that visual impairments alter image and video textures and their statistics. These measurements are performed regarding the statistics of the local binary pattern (LBP) operator and its extensions. We chosen LBP because it unifies traditional texture analysis models. In addition, LBP is a simple but effective algorithm that performs only fundamental operations, which favors fast and simple implementations, which is very useful for real-time image and video processing systems. Because of the abovementioned advantages, we analyzed the LBP operator and some of its state-of-the-art extensions addressing the problem of assessing image quality. Furthermore, we also propose new quality-aware LBP extensions to improve the prediction of quality. Then, we propose a framework for using these operators in order to produce new image quality metrics. Therefore, many no-reference image quality metrics can be generated from the proposed strategy. Inspired by experimental results of generated no-reference image quality metrics, we chosen a convenient texture operator to implement a full-reference video quality metric. In addition to the texture information, we also incorporate features including spatial activity, and temporal information. Experimental results indicated that our metric presents a superior performance when tested on several benchmark video quality databases, outperforming current state-of-the-art full-reference video quality metrics.

Pełny tekst źródłaENGLISH ABSTRACT: The main topics of study in this thesis are the Principal Component Analysis (PCA) and Canonical Variate Analysis (CVA) biplots, with the primary focus falling on the quality measures associated with these biplots. A detailed study of different routes along which PCA and CVA can be derived precedes the study of the PCA biplot and CVA biplot respectively. Different perspectives on PCA and CVA highlight different aspects of the theory that underlie PCA and CVA biplots respectively and so contribute to a more solid understanding of these biplots and their interpretation. PCA is studied via the routes followed by Pearson (1901) and Hotelling (1933). CVA is studied from the perspectives of Linear Discriminant Analysis, Canonical Correlation Analysis as well as a two-step approach introduced in Gower et al. (2011). The close relationship between CVA and Multivariate Analysis of Variance (MANOVA) also receives some attention. An explanation of the construction of the PCA biplot is provided subsequent to the study of PCA. Thereafter follows an in depth investigation of quality measures of the PCA biplot as well as the relationships between these quality measures. Specific attention is given to the effect of standardisation on the PCA biplot and its quality measures. Following the study of CVA is an explanation of the construction of the weighted CVA biplot as well as two different unweighted CVA biplots based on the two-step approach to CVA. Specific attention is given to the effect of accounting for group sizes in the construction of the CVA biplot on the representation of the group structure underlying a data set. It was found that larger groups tend to be better separated from other groups in the weighted CVA biplot than in the corresponding unweighted CVA biplots. Similarly it was found that smaller groups tend to be separated to a greater extent from other groups in the unweighted CVA biplots than in the corresponding weighted CVA biplot. A detailed investigation of previously defined quality measures of the CVA biplot follows the study of the CVA biplot. It was found that the accuracy with which the group centroids of larger groups are approximated in the weighted CVA biplot is usually higher than that in the corresponding unweighted CVA biplots. Three new quality measures that assess that accuracy of the Pythagorean distances in the CVA biplot are also defined. These quality measures assess the accuracy of the Pythagorean distances between the group centroids, the Pythagorean distances between the individual samples and the Pythagorean distances between the individual samples and group centroids in the CVA biplot respectively.
AFRIKAANSE OPSOMMING: Die hoofonderwerpe van studie in hierdie tesis is die Hoofkomponent Analise (HKA) bistipping asook die Kanoniese Veranderlike Analise (KVA) bistipping met die primêre fokus op die kwaliteitsmaatstawwe wat daarmee geassosieer word. ’n Gedetailleerde studie van verskillende roetes waarlangs HKA en KVA afgelei kan word, gaan die studie van die HKA en KVA bistippings respektiewelik vooraf. Verskillende perspektiewe op HKA en KVA belig verskillende aspekte van die teorie wat onderliggend is tot die HKA en KVA bistippings respektiewelik en dra sodoende by tot ’n meer breedvoerige begrip van hierdie bistippings en hulle interpretasies. HKA word bestudeer volgens die roetes wat gevolg is deur Pearson (1901) en Hotelling (1933). KVA word bestudeer vanuit die perspektiewe van Linieêre Diskriminantanalise, Kanoniese Korrelasie-analise sowel as ’n twee-stap-benadering soos voorgestel in Gower et al. (2011). Die noue verwantskap tussen KVA en Meerveranderlike Analise van Variansie (MANOVA) kry ook aandag. ’n Verduideliking van die konstruksie van die HKA bistipping word voorsien na afloop van die studie van HKA. Daarna volg ’n indiepte-ondersoek van die HKA bistipping kwaliteitsmaatstawwe sowel as die onderlinge verhoudings tussen hierdie kwaliteitsmaatstawe. Spesifieke aandag word gegee aan die effek van die standaardisasie op die HKA bistipping en sy kwaliteitsmaatstawe. Opvolgend op die studie van KVA is ’n verduideliking van die konstruksie van die geweegde KVA bistipping sowel as twee veskillende ongeweegde KVA bistippings gebaseer op die twee-stap-benadering tot KVA. Spesifieke aandag word gegee aan die effek wat die inagneming van die groepsgroottes in die konstruksie van die KVA bistipping op die voorstelling van die groepstruktuur onderliggend aan ’n datastel het. Daar is gevind dat groter groepe beter geskei is van ander groepe in die geweegde KVA bistipping as in die oorstemmende ongeweegde KVA bistipping. Soortgelyk daaraan is gevind dat kleiner groepe tot ’n groter mate geskei is van ander groepe in die ongeweegde KVA bistipping as in die oorstemmende geweegde KVA bistipping. ’n Gedetailleerde ondersoek van voorheen gedefinieerde kwaliteitsmaatstawe van die KVA bistipping volg op die studie van die KVA bistipping. Daar is gevind dat die akkuraatheid waarmee die groepsgemiddeldes van groter groepe benader word in die geweegde KVA bistipping, gewoonlik hoër is as in die ooreenstemmende ongeweegde KVA bistippings. Drie nuwe kwaliteitsmaatstawe wat die akkuraatheid van die Pythagoras-afstande in die KVA bistipping meet, word gedefinieer. Hierdie kwaliteitsmaatstawe beskryf onderskeidelik die akkuraatheid van die voorstelling van die Pythagoras-afstande tussen die groepsgemiddeldes, die Pythagoras-afstande tussen die individuele observasies en die Pythagoras-afstande tussen die individuele observasies en groepsgemiddeldes in die KVA bistipping.

Pełny tekst źródłaThe existing INFOCON system is an information warning system that the DOD maintains. It is not formally correlated to other warning systems, such as DEFCON, FPCON/THREATCON, WATCHCONs, SANS INFOCON, or the Homeland Security Advisory System Threat condition. The criteria for each INFOCON level are subjective. The INFOCON recommended actions are a mix of policy and general technical measures. The INFOCON system vaguely follows the Defense in Depth network defense methodology. This thesis examines the foundations for the existing INFOCON system and presents an evolved INFOCON system. The focus will be on the security of the DOD information infrastructure and the accomplishment of the mission, as well as the usability and the standardization of the INFOCON warning system. The end result is a prototype that is a set of predefined escalation scripts for the evolved INFOCON system's safeguard measures.

Pełny tekst źródłaThe integrated Network Enhanced Telemetry effort (iNET) was launched to create a telemetry network that will enhance the traditional point-to-point telemetry link from test articles (TAs) to ground stations (GS). Two of the critical needs identified by the Central Test and Evaluation Investment Program (CTEIP) are, "the need to be able to provide reliable coverage in potentially high capacity environments, even in Over-The-Horizon (OTH) settings", and "the need to make more efficient use of spectrum resources through dynamic sharing of said resources, based on instantaneous demand thereof". Research conducted at Morgan State University (MSU) has focused on providing solutions for both critical problems. The Mixed Network architecture developed by MSU has shown that a hybrid network can be used to provide coverage for TAs that are beyond the coverage area of the GS. The mixed network uses clustering techniques to partition the aggregate network into clusters or sub-networks based on properties of each TA, which currently include signal strengths, and location. The paper starts with a detailed analysis of two parameters that affect the performance of each sub-network: contention between the TAs in the mobile ad-hoc network, and queuing at the Gateway TAs that serve as the link between the mobile ad-hoc and the Cellular networks. Contention and queuing will be used to evaluate two performance (distance) measures for each sub-network: throughput and delay. We define a new distance measure known as "power", which is equal to the ratio of throughput over delay, and is used as a measure of performance of the mixed network for Quality of Service (QOS). This paper describes the analytical foundation used to prove that the "power" performance measure is an excellent tool for optimizing the clustering of a mixed network to provide QOS.

Les études portant sur la sclérose en plaque (SP) visent particulièrement des résultats pouvant améliorer la qualité de vie des personnes. En effet, la sclérose en plaque (SP) est une condition neurologique chronique qui affecte principalement de jeunes adultes. Cette maladie résulte en de sévères symptômes. Une meilleure compréhension de la gestion de ces symptômes dépend principalement de la précaution et de la précision des évaluations. Les mesures de qualité de vie reliée à la santé (QRVS) devraient représenter tous les domaines de ce qu'est la QRVS. De plus, ces mesures devraient se référer à un modèle théorique définit. L'objectif principal de cette étude est d'estimer à quel point les mesures évaluant la qualité de vie reliées à la santé (QVRS) utilisées pour la sclérose en plaque permettent de saisir l'entièreté des domaines de la QVRS. Chaque item de ces mesures sera analysé en utilisant comme référence le modèle Classification internationale du fonctionnement, du handicap et de la santé (CIF) et le modèle Wilson-Cleary. Selon une méthodologie standardisée, vingt-cinq professionnels de la santé ont reliés au modèle ICF les items de 10 questionnaires évaluant la QVRS. Parmi ces 550 items, 44% représentaient des symptômes, 34% représentaient le niveau de fonctionnement, 35% portaient sur la conception de la santé et la satisfaction par rapport à la vie. Seuls 6% portaient sur des facteurs environnementaux. Les différents aspects de la QVRS étaient représent
