I don't think there is any simple way. Sorry.
You can look at how they compare images in CBIR (Content based Image Retrieval) where they compare the outputs of SIFT or SURF algorithms. I don't think any of those algorithms could be called "simple".

A very common similarity measurement is SSIM http://en.wikipedia.org/wiki/Structural_similarity
