Abstract

The H.265/HEVC standard is state-of-the-art solution in the field of video compression. It utilizes various techniques to maximize achieved compression efficiency, including quad-tree syntax organization and powerful prediction algorithms. The quad-tree approach allows the flexible adaptation to various texture characteristics at the expense of the dramatic increase in computational complexity. This results in very long encoding times, especially while using the reference software, known as HM. However, over the years, miscellaneous heuristics were developed to accelerate the selection of the optimal CTU division and the prediction mode. This paper is an overview of the most promising heuristics, designed for intra frames.
