Design of Computation-Aware Mode Decision Scheme for H.264/AVC

Mode decision is a kernel function of current video standards, especially while dealing with massive coding modes as the latest H.264/AVC variable block size partitions. The mode decision process is extremely time consuming because it contains the kernel motion estimation and intra prediction modules. By applying the concepts of using priority coding orders to encode a sequence, this paper concludes a set of mode decision strategies with observation among priority lists. A computation-aware mode decision scheme is then proposed to the H.264/AVC. As the results demonstrated, coding with priority orders can achieve computation-aware ability automatically and the priority info is very helpful for developing software-based computation-aware mode decision algorithms
