요약서:
(EN) The embodiments of the present disclosure provide an intra-frame prediction method and apparatus, and a storage medium. The method comprises: determining main pixel directions of respective reference encoded blocks among reference encoded blocks that are spatially adjacent to a target encoded block; respectively searching for intra-frame prediction directions within a set numerical value from respective main pixel directions, and obtaining the searched intra-frame prediction directions corresponding to the respective main pixel directions; forming candidate intra-frame prediction directions with respective main pixel directions at least according to the searched intra-frame prediction directions corresponding to the respective main pixel directions; performing prediction encoding on the target encoded block according to the respective candidate intra-frame prediction directions, and determining the target intra-frame prediction direction from the respective candidate intra-frame prediction directions according to prediction encoding results corresponding to the respective candidate intra-frame prediction directions. The embodiments of the present disclosure can reduce the complexity in selecting the target intra-frame prediction direction in an intra-frame prediction process, so that the complexity of video encoding is reduced, and the real-time requirement of video encoding is satisfied.
(FR) Les modes de réalisation de la présente invention concernent un procédé et un appareil de prédiction intra-trame, un dispositif de codage vidéo, et un support de stockage. Le procédé consiste à : déterminer des directions de pixels principales de blocs codés de référence respectifs parmi des blocs codés de référence qui sont spatialement adjacents à un bloc codé cible ; rechercher respectivement des directions de prédiction intra-trame à l'intérieur d'une valeur numérique définie à partir de directions de pixels principales respectives, et obtenir les directions de prédiction intra-trame recherchées correspondant aux directions de pixels principales respectives ; former des directions de prédiction intra-trame candidates avec des directions de pixels principales respectives au moins selon les directions de prédiction intra-trame recherchées correspondant aux directions de pixels principales respectives ; exécuter un codage de prédiction sur le bloc codé cible selon les directions de prédiction intra-trame candidates respectives, et déterminer la direction de prédiction intra-trame cible à partir des directions de prédiction intra-trame candidates respectives selon des résultats de codage de prédiction correspondant aux directions de prédiction intra-trame candidates respectives. Les modes de réalisation de la présente invention peuvent simplifier la sélection de la direction de prédiction intra-trame cible dans un processus de prédiction intra-trame, ce qui réduit la complexité du codage vidéo et répond aux exigences en temps réel du codage vidéo.
(ZH) 本公开实施例提供一种帧内预测方法、装置及存储介质,该方法包括:确定目标编码块空间相邻的参考已编码块中,各参考已编码块的像素主方向;分别搜索距各像素主方向设定数值内的帧内预测方向,得到各像素主方向对应搜索到的帧内预测方向;至少根据各像素主方向对应搜索到的帧内预测方向,与各像素主方向形成候选帧内预测方向;分别根据各候选帧内预测方向对目标编码块进行预测编码,根据各候选帧内预测方向分别对应的预测编码结果,从各候选帧内预测方向中确定目标帧内预测方向。本公开实施例可降低帧内预测过程中,目标帧内预测方向的选择复杂度,使得视频编码的复杂度降低,满足视频编码的实时性要求。
