Abstract

o presente pedido refere-se a um método implementado por computador para identificar um canal entre pelo menos dois objetos a partir de dados de imagem que compreendem uma pluralidade de pixels ou voxels. o método compreende um ciclo com as etapas de escolher uma porção dos dados de imagem que contêm dados de imagem de pelo menos uma parte de pelo menos dois dos objetos, calcular gradientes de imagem dos pixels ou voxels da porção dos dados de imagem e analisar uma orientação dos gradientes de imagem. se pelo menos dois dos gradientes de imagem apontam para direções opostas, a porção escolhida dos dados de imagem é determinada para conter margens dos objetos que definem o canal. esse método pode ser usado subsequentemente para separar ou segmentar objetos ou partes dos objetos que definem o canal.
