The H.264/AVC improves the coding performance by employing the rate distortion optimization(RDO) in intra-frame coding.To achieve the optimal effect,all of the intra prediction modes are calculated,so the computational complexity increases dramatically.In order to reduce the coding time,a fast and effective intra-frame coding algorithm is proposed.The direction error strengths of texture are computed to reduce the number of the prediction modes,and an early termination criterion for early detecting zero-blo...
