Abstract: Automatic fingerprint identification provides an effective way for personal identification. The direction information in fingerprint images is very useful for fingerprint preprocessing ,classification and matching.This paper presents an algorithm which directly computes the direction image on the gray level images. Experimental results show that it is feasible for fingerprint processing.
