Hello, im trying to enhance fingerprint image using gabor filter. I have already estimated the orientation field and local frequency and according to this constructed the Gabor filter. I divided image into non-overlaping blocks of size WxW and applied appropriate filter into each block using convolution (conv2)...but the output image isnt good and ridges are usually broken at the boarders of blocks.
I have searched internet a lot, but didnt find answer. What am i doing wrong? And what are the correct steps in applying gabor filter on fingerprint?
Thanks :)
