The disparity calculation based on the permeability of the information contained in a video stereo

摘要

Method of calculating the disparity of stereo content, namely a digital stereo video, digital images, stereo frames of a film print scanned through a system live broadcast in real time or via a storage medium such as a hard drive, scanner, optical disk or the like, of the left view and right view of at least two chambers, comprising the following successive steps: - for each pixel of said left and right view view, carrying out the calculation of the constants permeability in the up, down, left and right, comparing the intensity values ​​of a relevant pixel and a neighboring pixel in the left direction, right, up and down (10, 20), - calculating values cost for each pixel, based on color differences between pixels of the left and right (30) views, - for each pixel of said left and right eye view, calculating values ​​added cost using a permeability constants and values ​​calculated cost (40, 50, 60, 70), - minimizing the cost function for each pixel, minimizing values ​​added cost within a support region to assign an initial disparity map to the left and right views (80), wherein the permeability constants for each pixel in four directions, corresponding to a μ value between 0 are calculated and 1, by the following equation:
