A framework of building complexity scalable and cost-effective algorithms for HEVC

Abstract

More and more inter-frame technologies are adopted in the latest video coding standard HEVC in the aim of improving coding efficiency, which also greatly increase the encoder complexity as well. For application scenarios with constrained and varying computing resources, e.g. portable devices or real-time visual communications, degradation on rate-distortion (R-D) performance is inevitable. How to maximize the R-D performance with constrained and varying computing resources is our main concern. In this paper, we will provide a new approach of building a complexity scalable and cost-effective framework consisting of three hierarchical levels. © 2012 Springer-Verlag Berlin Heidelberg.
