I am a 4th year software engineering student and I have to design and
programme a fingerprint recognition system. I am developing my project
in C# and have come across a problem which I have being stuck on for 2
months now. I am trying to find the orientation image of the
fingerprint so that I can later enhance the print and then be able to
extract the minutiae points with the direction of the minutiae points.
Basically the way I was doing it was to take every pixel and find the
orientation of the block of pixels around it using sobel. And do this
for every pixel. Then smooth it. But this is not working and maybe I
am doing it completely wrong.
If anyone could point me in the right direction i would be very
grateful.
Thnaks in advance.

Maybe you should try some Hough Transform on that image and use the
line information you'd obtain from that to extract a general image
orientation.
Or you can try some interpolation and derivative calculation on small
sets of pixel data .
In any case, you totally got the wrong forum for asking that :-).
This is a medical-information standards forum, not an image-processing
forum.
