Abstract

resumo método e dispositivo de vídeo para o processamento de um sinal de vídeo tridimensional, programa de computador, e, meio legível por computador um mapa de profundidade em um sinal de vídeo tridimensional [3d] é processado. a partir do sinal de vídeo 3d, um primeiro mapa de profundidade (z1) é derivado. um segundo mapa de profundidade (z2) é gerado por um filtro multidimensional (22) que faz com que o segundo mapa de profundidade tenha artefatos de espalhamento, enquanto o primeiro mapa de profundidade, em localizações correspondentes, tem menos ou nenhum de tais artefatos. uma diferença de profundidade é determinada entre o primeiro mapa de profundidade e o segundo mapa de profundidade, uma diferença de profundidade positiva indicando uma profundidade no segundo mapa de profundidade que está mais próximo de um espectador. um terceiro mapa de profundidade final é gerado pela combinação dos primeiros valores do mapa de profundidade e dos segundos valores do mapa de profundidade de acordo com uma função de combinação na dependência da diferença de profundidade. a função de combinação dá preferência aos primeiros valores onde a diferença de profundidade é positiva. 1/1
