Research about Optimized Video Coding of H.264 Based on Visual Attention

Abstract:

This paper puts forward and realizes an algorithm which optimize the video encoding based on human selective attention. The algorithm considering the influence of human visual attention area have on mode selection, correct the traditional pattern of full search algorithm, and find a more effective rapid method to determine the best encoding mode, so as to achieve the whole optimization of video coding algorithm. The experimental results show that the proposed algorithm can improve the subjective experience of the video sequence, effectively reduces the time of video encoding without significantly affect the PSNR.
