Abstract: A visual perception characteristics-combining hierarchical video coding method includes: setting priority of visual interest area and setting allocation scheme of video coding resource. Setting priority of visual interest area includes analyzing both time and space visual characteristic saliency of video content. Setting allocation scheme of video coding resource includes, according to the priority of visual interest area, macroblock coding resource of interest area is satisfied preferentially to realize hierarchical coding.

Abstract: The present disclosure relates to a method of acquiring neighboring disparity vectors for multi-texture and multi-depth video (e.g., 3D-HEVC video). The method belongs to the area of 3D-HEVC video coding technology. The method includes changing the standard associated with a disparity vector that is first searched as a final disparity vector. By deleting location which is minimum searched in candidate space and time location of the coding unit next to current coding unit to divide candidate space and time location of the coding unit into groups, the method takes searched disparity vector that is combined based on the proportion of adoption rate as final disparity vector. The method improves coding quality and at the same time maintaining origin fast algorithm efficiency. The embodiments of the present disclosure improve coding quality at least 0.05% and at the same time maintain origin fast algorithm efficiency while the decoding time is decreased to 97.1%.
