Abstract： |
The invention relates to a disparity vector acquiring method during a multi-view encoding process, and an encoding and a decoding method thereof. The invention comprises confirming a disparity vector between two views during the multi-view image encoding process, calculating to obtain a disparity vector between other two views according to the preceding disparity vector between two views and known relative position information of views, then performing multi-view encoding and decoding operations by means of the disparity vectors. The method of the invention, on one hand, primely utilizes the correlation between the disparity vector and the space object deep information, and on the other hand, primely utilizes the direct relation between the disparity vector and the position of each camera. Experiments show that the disparity vector between views can be precisely calculated during the multi-view encoding process, thereby effectively improving the multi-view encoding performance. |
