Disparity calculation using Loopy Belief Propagation

Context

The purpose of this work is to compute the disparity between two images (from which can be recovered the depth of field of the objects in the image).

Input

The input are two images of the same scene taken from two different points. Be careful, it is assumed that the two points differ only by an horizontal translation. Here are the two left and right tsukuba images used for the test :

Try with your own images by replacing the imgL.png and imgR.png files in the input folder.

Compute disparity

To compute the disparity map run :

python main.py

Don't forget to adjust your parameters at the beginning of main.py.

Find your disparity map in the output folder. Here is an example of disparity map :
