Abstract：Aiming at the problem that high efficiency video coding (HEVC )as a new generation of video coding standards increased the computation complexity and influenced the coding efficiency,a fast intra prediction algorithm was proposed.It used SAMD value and the depth of the adjacent encoded block to screen the block type selection.The experimental results showed that the algorithm provided averagely 40.95%reduction of intra coding time compared with the one accepted by HM5.0 with unimportant loss of PSNR and a slight increase of bite-rate.
