Many of the measurements that regionprops() can make can be used to compare shapes (contours). Print them out and see which are similar and which are different for the shapes you want to compare.

How about just subtracting them? Or use other metrics like SSIM? Or use SURF? Or go all out and use some sophisticated CBIR methods? I don't know the "diffusions mapping" method.
