摘要

A fast and hierarchical video coding method using lower coding information is proposed in this study. Firstly, a visual region of interest (VROI) detection algorithm is given based on the interdependency between in the coding information (inter-frame prediction mode, motion vector, etc.) and visual perception characteristics After that, visual interested priority is set and the hierarchical video coding method is developed according to the setting results. At last, different visual perception characteristic saliencies are the key to constitute the low complexity video coding framework. The simulation results show that the proposed hierarchical video coding method effectively alleviates the contradiction between complexity and accuracy. Compared with H.264/AVC (JM17.0), it reduces nearly 80% video coding time approximately and maintains a good video image quality and improves video coding performance significantly.
