N2 - High coding complexity is an obstruction when promoting the HEVC standard. In this paper, we propose a complexity control scheme for HEVC, which improves our previous work by employing a finer-grained complexity allocation scheme and mode sorting. In CTU-level complexity allocation, the time budget is allocated to each CTU proportionally to its estimated complexity. Then, the time budget for a CTU is further allocated to each CTU quadtree depth according to its probability of being the dominant depth. At last, a subset of modes are selected to reach the target complexity based on mode sorting. Compared with our previous work of which the least supported complexity ratio is 40%, the proposed scheme further reduces the lower bound of the ratio range to 20%.
