would like to perform a pre-processing in the following image I'm quite difficult to do this, someone can help me.The image quite gray and would isolate the digital fingerprint background noise, sorry my mistake, I only want to save the fingerprint, remove everything else into the picture.

Looks like you're already done then. All I see is a fingerprint. What constitutes "everything else"?

Looks like you need to do some research first for algorithms before you start coding. You can start here http://www.csse.uwa.edu.au/~pk/Research/MatlabFns/#fingerprints

This is the result of filtering your fingerprint image with a 75% black and 25% white filter. Is this sort of what you were looking for?
