Abstract

SEGMENTAÇÃO PARA EFEITOS DE IMAGEM. A presente invenção refere-se a sistemas, métodos e mídia legível por computador para segmentação de imagem de primeiro plano. Em alguns exemplos, um método pode incluir obter uma primeira imagem de um alvo e uma segunda imagem do alvo, a primeira imagem tendo um primeiro campo de visão (FOV) e a segunda imagem tendo um segundo FOV; determinar, com base na primeira imagem, um primeiro mapa de segmentação que identifica uma primeira região de primeiro plano estimada na primeira imagem; determinar, com base na segunda imagem, um segundo mapa de segmentação que identifica uma segunda região de primeiro plano estimada na segunda imagem; gerar um terceiro mapa de segmentação com base no primeiro mapa de segmentação e no segundo mapa de segmentação; e gerar, usando o segundo mapa de segmentação e o terceiro mapa de segmentação, uma máscara de segmentação refinada que identifica o alvo como uma região de primeiro plano da primeira e/ou segunda imagem.
