1. Criação de mapas de disparidades empregando análise multi-resolução e agrupamento perceptual / Disparity maps generation employing multi-resolution analysis and Gestalt Grouping
O trabalho apresentado por essa dissertação busca contribuir com a atenuação do problema da correspondência em visão estéreo a partir de uma abordagem local de soluções. São usadas duas estratégias como solução às ambigüidades e às oclusões da cena: a análise multi-resolução das imagens empregando a estrutura piramidal, e a força de agru

2. Modeling perceptual grouping and figure-ground segregation by means of active reentrant connections.
The segmentation of visual scenes is a fundamental process of early vision, but the underlying neural mechanisms are still largely unknown. Theoretical considerations as well as neurophysiological findings point to the importance in such processes of temporal correlations in neuronal activity. In a previous model, we showed that reentrant signaling among rhy

3. Image recognition: Visual grouping, recognition, and learning
Vision extracts useful information from images. Reconstructing the three-dimensional structure of our environment and recognizing the objects that populate it are among the most important functions of our visual system. Computer vision researchers study the computational principles of vision and aim at designing algorithms that reproduce these functions. Vis

4. Time-critical integration of formants for perception of communication calls in mice
Brain mechanisms in humans group together acoustical frequency components both in the spectral and temporal domain, which leads to the perception of auditory objects and of streams of sound events that are of biological and communicative significance. At the perceptual level, behavioral data on mammals that clearly support the presence of common concepts for
