An Efficient Mode Decision Algorithm Based on Dynamic Grouping and Adaptive Adjustment for H.264/AVC

Abstract

Abstract-The rate distortion optimization (RDO) enabled mode block), R(s, c, MODEIQP) is contributed by the number of decision (MD) is one ofthe most important techniques introduced by bits based on the MODE and QP. H.264/A VC. By adopting the exhaustive calculation of rate distortion, the optimal MD enhances the video encoding quality.A, -= 085X 2(QP-12)/3 (2) However, the computational complexity is significantly increased, MODEwhich is a key challenge for real-time and low power consumption applications. This paper presents a new fast MD algorithm for
