Research on Fast Algorithm of Mode Selection of H.264 Intra-Prediction
Zhu Li · Informatization Research · 2010
Mode selection of intra-prediction is the main factor affecting the coding rate of H.264.In this paper,an improved algorithm is proposed on the base of analyzing the research status of the fast algorithm of H.264 intra-prediction.Experimental results show that coding with all intra frame,the proposed algorithm introduces slight PSNR degradation and bit rate increase but saves around 12% of the total encoding time.
