Analysis of Coding Unit Size and Coding Depth for Class A Sequence in HEVC
High Efficiency Video Coding (HEVC) standard is the most recent video coding standard which outperforms its predecessors in terms of Bit Rate saving while maintaining the video quality. Flexible block partitioning structure is one of the prominent features of HEVC encoder. It overcomes limitations of H.264 such as limited block size or depth of partitioning. Even though it enhances performance of the encoder, it does add substantial computational load. In order to accelerate performance, we address the complexity reduction of block partitioning in HEVC in this paper. Thorough analysis of block partitioning structure with detailed results is presented for Class A test sequence.
