| Abstract: | H.264 intra prediction technology is the key of improving the video compression ratio.On the one hand,it can improve the I frame compression efficiency and is useful to control the rate of video stream,which has great significance in the actual network transmission;On the other hand,when the inter prediction work is failed matching block,intra prediction can be used and it has good compression effect.Intra prediction mode of H.264 is introducted,and the process of intra prediction mode election using RDO and the intra prediction parts of open source code X264 are shown. |
