There is something wrong in Descrip.m because I am getting zero for SUM=sum(v1-v2). Ideally, it should not be zero.

I am getting same descriptors for different images.
I tested it by:
image1 = imread('C:\Users\Explorer\Documents\MATLAB\ASL_signs\A.jpg');
image2 = imread('C:\Users\Explorer\Documents\MATLAB\ASL_signs\B.jpg');
v1=Descrip(image1);
v2=Descrip(image2);
SUM=sum(v1-v2)

Descrip writes then reads contour.jpg, and then computes the result from that. One way to set about debugging would be to see whether contour.jpg is different for the two images. That will help pin down where the problem lies.

The idea was that you run Descrip with one input image, look at contour.jpg, run it again with the other input image, and look at contour.jpg again. Are they different?

Don't use image as a variable name - it's the name of a built-in function.

If image A equals image B then I think they should be the same. You didn't attach either image so only you can know that. What did stepping through with the debugger reveal to you?

Watch out for the case where v1 and v2 are being returned as unsigned integers; in that case if v2 > v1 you would get "clipping" at 0 instead of getting a negative number.
