Abstract
La presente descripción proporciona métodos y dispositivos para la intra-predicción de un bloque actual en codificación o decodificación de video. El método comprende: realizar el procesamiento de intra-predicción del bloque actual de acuerdo con un modo de intrapredicción direccional, que comprende filtración de muestra de referencia o filtración de interpolación de subpíxel aplicado a muestras de referencia en uno o más bloques de referencia, en donde el modo de intra-predicción direccional se clasifica en uno de los siguientes grupos: (A) modos verticales u horizontales, (B) modos direccionales que incluyen modos diagonales que representan ángulos que son múltiplos de 45 grados, (C) modos direccionales restantes; si el modo de intra-predicción direccional se clasifica como que pertenece al grupo B, se aplica un filtro de muestra de referencia a las muestras de referencia; si el modo de intra-predicción direccional se clasifica como que pertenece al grupo C, se aplica un filtro de interpolación de muestra de referencia de intra a las muestras de referencia.
