摘要
介绍基于边缘检测的两种快速帧内预测算法,通过对两种算法在预测一致性方面的仿真,比较了它们在预测精度上的差异,对基于区域边缘强度的快速算法进行了分析和仿真,并提出了一种改进的快速帧内预测算法。
Introduced according to two kinds of fast intra prediction algorithms of edge examination first, then pass is predict to two kinds of algorithms imitate of consistency really compared them is predict the difference of accuracy. Finally to carried on analysis and imitate really according to the fast algorithm of district edge strength, and an improved fast algorithm for intra prediction is proposed.
