Please run the matlab script FindDepthEdges

No parameter settings are required.

----------------------------
The input for our algorithm are the images 'left.bmp', 'right.bmp',
'up.bmp', 'down.bmp', located in the same directory of FindDepthEdges.m

The output is the image without shadows, the depth edge confidence map 
and the thresholded confidence map. Bmp files with these results will be
created in the same directory.
