Abstract

Cuando se realiza un procedimiento de predicción intra cuadro para generar una imagen de intra predicción utilizando una señal de imagen ya codificada en un cuadro, una pare de intra predicción 4 se refiere a un cuadro para la selección de filtro para seleccionar un filtro de uno o más filtros, los cuales son preparados por adelantado de acuerdo con los estados de los diversos parámetros asociados con la codificación de un bloque objetivo a ser filtrado y realiza un procedimiento de filtración sobre la imagen de predicción utilizando el filtro; como resultado, los errores de predicción que ocurren localmente son reducidos, y se puede mejorar la calidad de la imagen.
