A GUI demonstrates an efficient stereo matching algorithm.

File Information


This function performs the computationally expensive step of matching two rectified and undistorted stereo images. The output is a dense disparity map. If camera parameters are known, this allows for three dimensional reconstruction.

Two graphical user interfaces demonstrate the algorithm.

Please note this function requires the Image Processing Toolbox!

[spdmap, dcost, pcost, wcost] = stereomatch(imgleft, imgright, windowsize, disparity, spacc)

The standard images included are from
[1] D. Scharstein and R. Szeliski. A taxonomy and evaluation of dense two-frame stereo correspondence algorithms. International Journal of Computer Vision, 47(1/2/3):7-42, April-June 2002.

Thank you for your code. How can I set the right image as the reference image? Thank you!

The "reconstruction" image is "upside down" compared to the reference and target.

nice GUI and coding... what if I want to test my own images?

There seems to be an error in the integral image technique. The filtering window should be

h = zeros(WS+2,WS+2,'double');
h(1,1) = 1; h(1,WS-1) = -1;
h(WS-1,1) = -1; h(WS-1,WS-1) = 1;

that is, for a 3x3 summing window, the filtering window must be 5x5 to implement the algorithm correclty (see and note that points A, B and C are outside the summing window)

I tested this with a simple matrix for validation. Otherwise, thanks for the useful code.

This program shows a disparity map but if i want to save the disparity map to a file how can I do that ?

The file works very well. Just run stereovision.m it will come up with a GUI.

Please give instructions on how to run. Code doesnt run nor do fig files.
