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. Proposta de implementação em hardware para o algoritmo non-local means.
Imagem digital é a representação de uma imagem bidimensional usando números binários codificados de modo a permitir seu armazenamento, transferência, impressão ou reprodução, e seu processamento por meios eletrônicos. É formada por um conjunto de pontos definidos por valores numéricos, escala de cinza, no qual cada ponto representa um pixel. Em q

3. Adaptive image denoising using scale and space consistency
This paper proposes a new method for image denoising with edge preservation, based on image multiresolution decomposition by a redundant wavelet transform. In our approach, edges are implicitly located and preserved in the wavelet domain, whilst image noise is filtered out. At each resolution level, the image edges are estimated by gradient magnitudes (obtai

4. Combinação de modelos de campos aleatórios markovianos para classificação contextual de imagens multiespectrais / Combining markov random field models for multispectral image contextual classification
This work presents a novel MAP-MRF approach for multispectral image contextual classification by combining higher-order Markov Random Field models. The statistical modeling follows the Bayesian paradigm, with the definition of a multispectral Gaussian Markov Random Field model for the observations and a Potts MRF model to represent the a priori knowledge. In

5. An-edge preserving multigrid-like for image denoising and inpainting / Uma técnica multimalhas para eliminação de ruídos e retoque digita"
Techniques based on the Well-Balanced Flow Equation have been employed as an efficient tool for edge preserving noise removal. Although effective, this technique demands high computational effort, rendering it not practical in several applications. This work aims at proposing a multigrid-like technique for speeding up the solution of the Well- Balanced Flow
