Abstract

The print is scanned in and enhanced using a 2 dimensional filter which is implemented using a 2D Fourier transform. The image is then thresholded to a binary image. The fingerprint ridges are simultaneously thinned and traced by a line-following technique to obtain a skeletonised image. During this process, the positions of certain types of minutiae are detected. These minutiae are then compared to a previously stored template to verify the identity of the user. The template matching procedure is robust against translation and rotation of the fingerprint
