Abstract

Un filtro de repetición 6 incluye una unidad de clasificación de región 12 para extraer una cantidad característica de cada una de las regiones que construyen una imagen decodificada local para clasificar cada una de las regiones en la clase a la cual pertenece la región de acuerdo con la cantidad característica, y una unidad de diseño y procesamiento de filtro 13 para cada clase a la cual pertenece una o más regiones entre las regiones, las cuales construyen la imagen decodificada local, generando un filtro Wiener el cual reduce al mínimo un error que ocurre entre una imagen ingresada y la imagen decodificada local en cada una de las una o más regiones que pertenecen a la clase para compensar una distorsión sobrepuesta sobre la una o más regiones utilizando el filtro Wiener.
