Optimal Adaptive Quantization Based on Temporal Distortion Propagation Model for HEVC.

Optimal adaptive quantization is one of the key points to optimize the coding efficiency of video encoders. The latest block-based video compression standards, such as high-efficiency video coding (HEVC), extensively use predictive coding techniques that create dependencies between blocks and increase the complexity of optimal block quantizers search. Specifically, the motion compensation is responsible for a dependency network connecting all blocks of the same GOP together.
