Abstract

Un método para procesar uno o más videos de una escena en 3D, en el que cada video es adquirido por una cámara correspondiente dispuesta en una pose particular, que comprende para cada bloque actual en una imagen actual (515) a procesar las etapas de: obtener (410) un vector de movimiento o de disparidad (503) a partir de bloques vecinos (501) del bloque actual; determinar (420) un bloque de profundidad (505) para el bloque actual a partir de un componente de profundidad correspondiente de una imagen de referencia sobre la base del vector de movimiento o de disparidad (503) obtenido a partir de los bloques vecinos (501) del bloque actual; sintetizar (430), usando distorsión hacia atrás (506), un campo de movimiento correspondiente a una visión actual sobre la base de una imagen de referencia correspondiente a una visión de referencia y el bloque de profundidad determinado (505); y codificar (440) predictivamente el bloque actual usando el campo de movimiento, en donde las etapas (410, 420, 430, 440) se realizan en un procesador.
