Abstract

DETECÇçO DE BORDA EM IMAGENS DE ULTRA-SOM. As modalidades da presente invenção aperfeiçoam a detecção de borda nos dados de imagem bidimensional que pode ser realizada automaticamente com o envolvimento mínimo do usuário. A invenção é realizada automaticamente, utilizando uma técnica de processamento de imagem que resulta na geração de um contorno de borda segmentada, que pode então ser utilizada na reconstrução e segmentação tridimensional.
