摘要:
An intra prediction method according to the present invention comprises the following steps: performing a directional prediction using at least one of a neighboring pixel of a current block and a left upper corner pixel positioned at a left upper corner of the current block so as to obtain a first prediction value for the current block; obtaining a second prediction value for the current block using the reference sample positioned in the current block; and weighted summing the first prediction value and the second prediction value using a weighting matrix so as to obtain a final prediction value for the current block. According to the present invention, image encoding/decoding efficiency may be improved.
摘要(中):
根据本发明的帧内预测方法包括以下步骤:使用位于当前块的左上角的当前块的相邻像素和左上角像素中的至少一个来执行方向预测,以获得 当前块的第一预测值; 使用位于当前块中的参考样本获取当前块的第二预测值; 并使用加权矩阵对第一预测值和第二预测值进行加权求和,以获得当前块的最终预测值。 根据本发明,可以提高图像编码/解码效率。
