Abstract
(EN)
A method for determining a prediction direction, a decoder, and a computer storage medium. The method is applicable in the decoder. The method comprises: acquiring a DM mode in a chrominance intraframe prediction mode of a block to be decoded (S101); and, determining an index number of a prediction direction of a DM derivation mode on the basis of index number M of a prediction direction of the DM mode and of preset offset N to determine the DM derivation mode (S102).
(FR)
L'invention concerne un procédé de détermination d'une direction de prédiction, un décodeur et un support d'informations informatique. Le procédé est applicable dans le décodeur. Le procédé consiste : à acquérir un mode DM dans un mode de prédiction intra-image de chrominance d'un bloc à décoder (S101) ; et à déterminer un indice d'une direction de prédiction d'un mode de dérivation DM en fonction d'un indice M d'une direction de prédiction du mode DM et d'un décalage prédéfini N permettant de déterminer le mode de dérivation DM (S102).
(ZH)
一种预测方向的确定方法、解码器以及计算机存储介质,所述方法应用于一解码器中,所述方法包括:获取待解码块的色度帧内预测模式中DM模式(S101);根据DM模式的预测方向的索引号M和预设的偏移量N,确定DM推导模式的预测方向的索引号,以确定DM推导模式(S102)。
