Real-Time Disparity Map Computation Based On Disparity Space Image

The current paper proposes a real-time dense stereo matching algorithm based on a DSI (Disparity Space Image ) data structure that can produce accurate disparity map. Our approach divides the disparity map computing into two main steps. The first step deals with the computing of the initial disparity map using DSI method. The second step presents a simple and a fast method to refine the initial disparity map. New strategies and improvements are introduced so that an accurate and fast result can be reached. Experimental results on real data sets were conducted for evaluating the solutions proposed. Also, a comparative evaluation of our method with others methods is presented.
