Hello,

This is my first time to ask the question on this mathforum.
I am not getting how to implement the orientation field estimation
algorithm for a fingerprint image.

First we have to divide the input fingerprint image into blocks of
size 10*10.

then compute the gradients Gx and Gy at each pixel in each block.
(do not use the gradient function in matlab)

I anybody help me for these two setps only.

You can send me code on abhijeet...@rediffmail.com
Thanks

You can use the gradient function in matlab..do it for the entire
image, and then process block by block (the averaging of gradients
etc).

You can refer to Bazen's paper for the algorithm

abhijeet has only ever posted once to this newsgroup, but it was only
6 years ago so I'm sure he's still monitoring the newsgroup waiting
for a question like yours. You should get a response shortly. Hang
in there.

You can look at my code:

http://www.mathworks.com/matlabcentral/fileexchange/29280-fingerprint-matching-algorithm-using-shape-context-and-orientation-descriptors

I use orientation estimation (global orientation image) for one of my descriptors.

Can someone post a link to Bazen's paper or provide the title of the paper as a quick google search doesn't seem to find anything? Or alternatively, tell me which file in the fingerprint set of files calculates the gradient of each x,y pixel in an image? Any help would be much appreciated.

Can anyone help me with coding to find the orientation of fingerprint using gradient function??
