Abstract
High Efficiency Video Coding (HEVC) is the latest video coding standard and has achieved 50% better compression performance compared to prior video standards competing with (2K, 4K, and 8K) video resolutions. HEVC adopts flexible quad-tree structure, resulting 60% of inter prediction complexity. A fast coding unit decision taking algorithm is proposed which can reduce the coding tree unit (CTU) inter mode complexity of HEVC, by enlarging the coding unit (CU), prediction unit (PU) and transform unit (TU) sizes. The algorithm first extends the coding unit size and then classifies it into different units with respect to the information collected from previous encoded frames. The probability model is used to take decision for the splitting of coding unit. Experimental results achieved an average reduction of encoding time by 62% with an average decrease of 0.01% dB in PSNR and negligible bit-rate increment.
