First of all:

Matching signatures is one of THE most difficult tasks. Why? Because each signature is different. Even if you compare the same signatures, the probability of them being the same is very less. So in your case, you will have to decide the threshold value.

About the method:

A very simple and crude algorithm might comprise of the following steps:

1.Divide the image into strips. Both the images, i.e. both the inputs.

2.Match the corresponding strips and find the similarity.

On the basis of the threshold decide if the images are same or not.

I know this is an old post but im trying to figure out something along the lines of this. What route did you end up taking? Also how did you go about taking images of various sizes and normalizing them to be compared?
