H.264 인트라 프레임의 Rate Distortion 성능 향상을 위한 모드 결정 기법

초록

In this paper, we present a improved rate distortion optimization (RDO) for H.264 intra coding. By using new mode decision criteria pass for I4x4 in company with the original RDO, the proposed method can achieve the better coding efficiency comparing with the original RDO. Our experimental results show that the proposed algorithm can archive about 0.64~1.6578% bit rate decrease at the same PSNR and 0.049~0.101㏈ PSNR increase at the same bit rate.
