Abstract

A method of analyzing and recognizing fingerprint images that utilizes vector processing of a vector field that is defined as the tangential vector of the fingerprint ridge curves is disclosed. The raw fingerprint image is divided into blocks (204), filtered to remove noise (208), and the orientation direction of each block is found (210). This allows the ridge curves to be enhanced and approximated by piece-wise linear approximations (218). The piece-wise linear approximations to the ridge curves allow the minutiae to be extracted (220) and classified and a fingerprint minutiae template (224) to be constructed. An enrollment process gathers multiple fingerprint images, creates fingerprint minutiae templates (110) corresponding to the acquired fingerprint images, and stores the templates (112) and other data associated with the respective individual or the enrolled fingerprint in a fingerprint database.
