AI Technical Summary
Technical Problem
[0006]本申请提供一种帧内预测方法、编码器及存储装置，能够解决现有技术中帧内预测过程中空间冗余性的去除效果有限的问题
Benefits of technology
[0015]本申请的有益效果是：通过在当前编码块的相邻第一侧、第二侧定义至少m条参考线；对当前编码块中的当前像素利用一侧的多条参考线进行单向预测，如此每个当前编码块中的像素的角度模式预测值的获取考虑到了该像素与至少两条参考线之间的相关性，参考像素的分布范围更大，从而提高选出最优的帧内预测模式的可能性，改善空间冗余性的去除效果。

Abstract
The application discloses an intra-frame prediction method, an encoder and a storage device. The intra-frame prediction method comprises the following steps: defining at least m reference lines on a first side and a second side of a current coding block, wherein the at least m reference lines comprise at least one first reference line on the first side and at least one second reference line on the second side; determining a first prediction value of a current pixel in the current coding block on one side, and taking the first prediction value as an angle mode prediction value of the current pixel; wherein the one side comprises the first side or the second side. Through the above method, the removal effect of spatial redundancy can be improved.
