Title in Portuguese
Segmentação e detecção de simetria em imagens via redes de mapas acoplados.
Keywords in Portuguese
Processamento de imagens
Redes de mapas acoplados
Sistemas dinâmicos
Abstract in Portuguese
Sincronismo é um comportamento dinâmico que pode ser detectado na atividade dos neurônios que formam estruturas corticais, e essa atividade parece ser fundamental para a realização de processos relacionados a aprendizado, compreensão e reconhecimento. Estruturas corticais podem ser modeladas por redes de mapas acoplados. Nessas redes, a existência de solução síncrona é determinada pela equação que governa a atividade de cada mapa, pela topologia de acoplamento entre os mapas e pelos valores dos parâmetros. O enfoque deste trabalho é empregar redes de mapas acoplados voltados à detecção de simetria, e segmentação de imagens, via sincronismo.

Abstract in English
Synchronism is a dynamical behavior that can be found in the neural activity of cortical structures, and this behavior seems to be fundamental in learning, understanding and recognition processes. Cortical structures can be modeled by using coupled map lattices. In such lattices, the existence of synchronous solution is determined by the equation that rules the activity of each map, by the coupling topology among the maps, and by the parameter values. The goal of this work is to employ coupled map lattices in symmetry detection and image segmentation, via synchronism.
