1. Image segmentation and particles classification using texture analysis method
Introduction: Ingredients of oily fish include a large amount of polyunsaturated fatty acids, which are important elements in various metabolic processes of humans, and have also been used to prevent diseases. However, in an attempt to reduce cost, recent developments are starting a replace the ingredients of fish oil with products of microalgae, that also p

2. Optimization of image analysis techniques for quality assessment of whole-wheat breads made with fat replacer
The cellular structure of healthy food products, with added dietary fiber and low in calories, is an important factor that contributes to the assessment of quality, which can be quantified by image analysis of visual texture. This study seeks to compare image analysis techniques (binarization using Otsu’s method and the default ImageJ algorithm, a variatio

3. Implementação de uma arquitetura para binarização de imagens em FPGA / Implementation of an architecture for FPGA image binarization
In many imaging applications it is desirable that images are converted to grayscale images to binary, ie with only two intensity levels. To accomplish this task separation between two levels is necessary to calculate a threshold value as determined from it which pixels will belong to a level generally the object of interest, and which belong to another level

4. Diagnóstico da sífilis auxiliado por computador: proposta de um método híbrido fuzzy neural para análise de imagem de fluorescência. / Diagnosis of syphilis computer aided: proposal of a fuzzy neural hybrid method for image analysis of fluorescence.
In this work we have developed a prototype to analyze fluorescence microscopy images obtained from the FTA-ABS. This test is used as confirmation of the diagnosis of syphilis by identifying the bacteria causing the disease. A considerable problem in the analysis of such images is the subjectivity in the interpretation of fluorescence intensity shown, because

5. Projeto da arquitetura de hardware para binarização e modelagem de contextos para o CABAC do padrão de compressão de vídeo H.264/AVC / Hardware architecture design for binarization and context modeling for CABAC of H.264/AVC video compression
O codificador aritmético binário adaptativo ao contexto adotado (CABAC – Context-based Adaptive Binary Arithmetic Coding) pelo padrão H.264/AVC a partir de perfil Main é o estado-da-arte em termos de eficiência de taxa de bits. Entretanto, o CABAC ocupa 9.6% do tempo total de processamento e seu throughput é limitado pelas dependências de dados no n

6. Extração de minúcias em imagens de impressões digitais / Extraction minutiae in fingerprints
In this research a method for minutiae extraction in fingerprints images, based on classical approach of image binarization, is presented. The method is composed by three main modules: preprocessing, minutiae detection and post-processing. It was used fingerprint images from FVC2004 database (Fingerprint Verification Competition) that includes synthetic and

7. Um novo algoritmo baseado em entropia para filtragem da interferÃncia frente-verso / A New Entropy-Based Algorith for Back-to-Front Interference Filtering
The digitalization of documents originally printed in paper is the most efficient way one can find today to preserve their contents to future generations and to make them widely accessible including their dissemination via computer networks. The particular features of each set of documents impose different techniques to document storage and digitalization. I
