What is meant by Disparity Space Image (DSI). I couldn't find a clear definition for it. In some places it is mentioned that DSI and Disparity map are the same (but I disagree), like in here What is meant by disparity space image. And in some places it is shown as 3D matrix and is represented by C(x, y, d).
I want to know what exactly is DSI and how to calculate it given two stereo images.?

This print was taken from the free preview of the paper "Disparity-space images and large occlusion stereo" by Stephen S. Intille and Aaron F. Bobick and it perfectly answers your question.

So, the DSI for a single scanline results in a 2D matrix (x, disparity) and the disparity space image for the whole image will be a 3D matrix (x, y, disparity). – x.projekt Jan 28 '17 at 05:44
