How can we compare two images?
I want to know the percentage of matching between the two images. Please Help.

Define what _you_ mean by "the percentage of matching". For example, do you
consider the following two patches to match, to not match, or to match
partially?

patch([0 2; 1 3; 1 3; 0 2; 0 2], ...
[0 0; 0 0; 1 1; 1 1; 0 0], ...
cat(3, [1 0.999999], [0 0], [0 0]))
