Abstract

Cuando se lleva a cabo un proceso de predicción intra-cuadro para generar una imagen de intra-predicción usando una señal de imagen ya codificada en un cuadro, una parte de intra-predicción 4 selecciona un filtro de uno o más filtros que son preparados con anticipación de conformidad con los estados de varios parámetros asociados con la codificación de un bloque objetivo que ha de ser filtrado, y lleva a cabo un proceso de filtración sobre una imagen de predicción usando el filtro; como resultado, los errores de predicción que ocurren localmente pueden ser reducidos, y la calidad de imagen puede ser mejorada.
