Abstract
A system to generate a template of a fingerprint input image is described. The system provides for smoothing the input image, forming a binary image from it, and further processing the binary image to extract the minutia of the fingerprint. The minutiae are stored in the template, in the form of locations of each minutia in relation to all other minutiae. The system includes optional identification and verification steps, which compare the template generated according to the system with templates stored in a fingerprint database.
