Abstract :
I-frame affects image quality seriously, but costs enormous bits in video coding processing. In order to optimize the increasing bit rate caused by I-frame, we design a novel video codec based on residual image for the latest video coding standard HEVC. An appropriate method to obtain residual image is proposed depend on the characteristic analysis. The proposed codec reduces considerably by up to 16.1% bit rate compared to JCTVC benchmark HM10 while maintaining the same PSNR. Experimental results for various test sequences at different resolutions are presented to show the effectiveness of the proposed codec.
