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"?

ok. What I need is to study the characteristics of digital printing, which makes them unique for each person. So I would treat the fingerprint in order to highlight their characteristics such as minutiae. I would like to make the homogeneous background making clear the fingerprint, certain sections of the print can be eliminated or confused with the background.

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?
