Abstract

The high compression efficiency ensured by the JVT H.264 video coding standard is mostly based on the adoption of a variable block-size motion estimation and mode decision. However, these advanced features imply a remarkable increase in the encoder complexity. To face the complexity issues, a number of algorithms and techniques have been developed, with the aim to speed up both the processes. In this paper, one of the algorithms proposed for fast mode decision is reviewed and evaluated, with respect to the reference software implementation, and some improvements are suggested, in order to make its behavior adaptable to the video content
