Abstract
La presente invención se refiere a una señal de imagen que se codifica para reducir artefactos. En un cuadro de imagen original (F) se identifican una o más áreas de transición gradual (R), en un cuadro decodificado (F') correspondiente se identifican una o más áreas de transición gradual (R'), se establecen los parámetros funcionales CC) que describen el contenido de datos de una o más áreas de transición gradual del cuadro de imagen original y se establecen los datos de posición (P) para las posiciones de una o más áreas correspondientes (R') en el cuadro decodificado (F') . El reemplazo del contenido de las áreas R' en el cuadro decodificado con el contenido reconstruido de las áreas R en el cuadro original mejora la calidad del cuadro decodificado.
