The key of our method is to model the existence of discontinuity between every two adjacent pixels by the depth differences between that two pixels. At each pixel, we approximate the left and right (resp., upper and lower) partial derivatives and relatively weight the two approximations by comparing the depth differences at the left and right (resp., upper and lower) sides.
