Abstract:
1. A system of image stereo matching, comprising: at least one stereo matching unit (SMU) each being operable to receive a first view and a second view of a view pair, according to which the SMU is configured to generate a first depth map for the first view; a backward tracer operable to receive the first depth map, according to which a second depth map for the second view is derived by mapping depth data of the first depth map to a corresponding matching window displaced with corresponding disparity in the second view, the second depth map being derived by the backward tracer without using image data of the first view and the second view, wherein the first depth map is generated by determining similarity metrics between matching windows of the first view and the second view by the SMU, and the matching window has a size that is dynamically changed according to texture density of the first view; an image buffer configured to store image pixel values; an edge detector configured to obtain edge information of the first view; and a texture density unit configured to determine a window size of the matching window by comparing the edge information with at least one density threshold.
