Abstract

método de reconhecimento de cabeça. a presente invenção refere-se a um método para reconhceimento de uma cabeça humana em uma imagem de origem. o método compreende detectar um contorno de pleo menos parte de um corpo humano na imagem de origem, calculando uma profundidade do corpo na imagem de origem. a partir de uma imagem de origem, um tamanho de raio maior e um tamanho de raio menor de uma elipse correspondente a uma cabeça humana na profundidade é calculado, e para pelo menos vários de um conjunto de pixels do contorno detectado, gerar em uma matriz acumuladora pelo menos um segmento de uma elipse centrada na posição do pixel de contorno e possuindo o menor tamanhos de raio. as posições de locais de intensidade máxima na matriz acumuladora são selecionadas como correspondendo às posições das cabeças humanas candidatas na imagem de origem.
