Modelos de Contornos Deformáveis para Extração de Características em Imagens Carpais

Celso Olivete JúniorEvandro Luís Linhari Rodrigues

This paper presents a methodology for semi-automatic hand bones extraction from digitalimages using active contour models or Snake. The Active Contours Snake method is described by anenergy functional that contains external and internal image forces. After the initialization, the Snake curve moves until its energy is minimized. The method is initialized by an operator, who should supply a few seed points describing sparsely and coarsely the each hand bones. The mathematicalfundamentals of the method and experimental results are presented in this paper.
