摘要
Abstract
The method of Intra prediction for the current video coding standard mainly uses the pixels of the left, the top, the upper right neighboring blocks,and doesn't use the pixels of the right and lower blocks.It is not because there is low correlation between the current block and the right and lower blocks,but the right and lower blocks need to refer to the data of current block to decode the display.If the mode of the right block is the vertical mode, it can use the data of right block to predict the current block and a new prediction model of mean-left-right is presented.The corresponding adjustment is implemented for AVS encoder and decoder.Experimental results show that the PSNR increases about 0.02 dB and the coding bit rate decreases by about 1.22% with small complexity increasing.关键词
