Hi,

My name is Nabeel Younus. I am doing my research work on fingerprint matching. I have to detect the core point for matching. I was earlier stuck but recently I have studied the paper and started work. First step is to estimate the orientation.I am following Anil.K.Jains Technique. I estimated the orientation field according to algo. Next i tried to show image via ridgeorient.m file which is avalaible but results were not good ! . So i am posting my code. If anyone can figure out the problem or give the suggestions i will be really grateful bcz i think that i have implemented the algo correctly
