Abstract

Un método de descodificación de imágenes de acuerdo con el presente documento puede comprender los pasos de: recibir información de bandera que indique si se utiliza o no una intra predicción en base a matriz (MIP) con respecto a un bloque actual; recibir información de modo de intra predicción en base a matriz (MIP) sobre la base de la información de bandera; generar una muestra de intra predicción para el bloque actual sobre la base de la información de modo MIP; y generar muestras de restauración para el bloque actual sobre la base de las muestras de intra predicción.
