Information permeability based disparity estimation in stereo video

摘要

According to the invention a method for estimating disparity maps of left and right views of stereo content is described. The method comprises the following steps: calculating the permeability characteristics of each pixel in horizontal and vertical direction, in particular left and right as well as up and down, based on colour similarities with the neighbouring pixels to receive permeability constants of the left and right view; cost calculation for each pixel depending on colour differences between the pixels in the left and right view, wherein the cost values for each pixel are integrated in horizontal and vertical direction by considering the permeability constants in the left and right view; minimising the cost function for each pixel to assign an initial disparity map of the left and right view; cross checking the initial disparity maps based on occlusions of the left and right view to receive a final disparity map of the left and right view.
