Original Matlab Code, different results

[huig-]

Hi,

I am using the code from http://dde.binghamton.edu/download/camera_fingerprint/ with the same options (wiener, crop_center, level=4, sigma=5) and obtaining different results. Have you checked if the code is fine?

I haven't compared with that implementation. Can you point to which specifically differs?

I believe he is saying the resulting fingerprint from your code differs from the fingerprint obtained in the referenced implementation. I was about to try and code a python implementation of this myself but was happy when I saw you already had. Honestly, I didn't really understand the formulas from the white paper although I wish I knew how to read them.

As long as the uniqueness is the same, both implementations would work fine for the intended purpose. If you are using two different implementations together and they fingerprints didn't match, I could see how this could be a problem.
