Disparity compression

Our perceptual model for disparity can guide compression of disparity. Assuming a disparity image as input, we first convert physical disparity into perceived disparity. In perceptual space, disparity below one JND can be safely removed without changing the perceived stereo effect. More aggressive results are achieved when using multiple JNDs.
