Abstract
本申请实施例公开了一种帧内预测方法、编码器、解码器以及计算机存储介质，该方法包括：确定当前块的预测模式参数；当所述预测模式参数指示使用非矩形块复制INBC模式时，确定当前块的第一分区的第一目标块矢量信息和当前块的第二分区的第二目标块矢量信息；根据所述第一目标块矢量信息确定所述第一分区的第一预测值，以及根据所述第二目标块矢量信息确定所述第二分区的第二预测值；确定所述第一分区的第一权重值和所述第二分区的第二权重值；利用所述第一预测值、所述第一权重值、所述第二预测值和所述第二权重值进行加权融合，确定所述当前块的帧内预测值。这样，当使用INBC模式确定当前块的帧内预测值时，可以提升视频序列的编解码效率。
