I am working on pore extraction from binary fingerprint image, On using the watershed segmentation, I managed to get the gradient image but now I want to extract the pores(white blobs) from the ridges(the lines across the fingerprint).How do I go about?

3Your question may be too complex to be answered, it may help if you could give some overview of what you already tried and where your problems start. There are entire articles on the topic, perhaps [this one](http://de.scribd.com/doc/105723602/Fingerprint-Matching-Approach-Based-on-Bifurcation-Minutiae#scribd) may help you get started. – SaschaM78 Mar 11 '15 at 10:36

Thank you but my query is beyond minutiae and bifurcation. I am doing pores extraction from fingerprint image by using Marker Controlled Watershed Segmentation method proposed by S. Malathi et al. Unfortunately I cant share images due to the preconditions of the group. – user1 Mar 11 '15 at 18:31
