Im1 = rand(50,50)>0.2; % your first image
Im2 = rand(50,50)>0.6; % your transformed image
overlapIm = Im1 & Im2;
numSharedWhitePixels = nnz(overlapIm);
Is that what you were looking for?

If the images are not of the same size, you need to rethink what you're attempting to do. Why did it change size? Just what kind of transform are you doing? Maybe you can resize one of the images to match the other.
