Abstract:	摘要： This paper aims to improve the intra coding performance on H.264 and high efficient video coding (HEVC). A new intra prediction approach is proposed based on synthesizing two neighboring predictors. These two predictors are selected from different prediction directions and then the predicted block is generated by combining the two predictors using different weights. The weights for the predictors do not need to be saved, so the bit rate can be greatly reduced. The main contributions of this paper are proposing the following: 1) a highly efficient way and high compact compression to select the proper predictors; 2) a weight estimation method for the predictors; and 3) a reversible weight restoration method for the predictors to save the bit rate in the decoding phase. Experimental results show that the proposed method outperforms H.264/AVC and HEVC in intra prediction by 11.79% and 3.6%, respectively, in bitrate reduction. 其他題名： TMM 出版者： Piscataway: IEEE 出版日期： 2015-09 出處： IEEE Transactions on Multimedia, 2015-09, Vol.17 (9), p.1508-1514 資源來源： IEEE Electronic Library (IEL) 版權： Copyright The Institute of Electrical and Electronics Engineers, Inc.
