A Intra Prediction Mode Algorithm based on AVS
GE Ming-ming · Microcomputer Information · 2010
AVS video standard adopts the Rate Distortion Optimization(RDO)technique to improve the compression performance in the intra prediction,but AVS proposed intra prediction technology does not fully take into account the predicted pixel location accuracy of the forecast,it is not very accurate prediction. The paper proposes to an intra prediction based on reproducing kernel interpolation for improving intra prediction. The main idea is to present an reproducing kernel interpolation to work out and revise the prediction coefficients of some prediction modes. Experiments show that the proposed intra prediction scheme can improve the efficiency of intra frame coding and achieve better performance of intra prediction,compared with the original intra prediction scheme in AVS.
