摘要： 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.

摘要： 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, filtered to remove noise, and the orientation direction of each block is found. This allows the ridge curves to be enhanced and approximated by piece-wise linear approximations. The piece-wise linear approximations to the ridge curves allow the minutiae to be extracted and classified and a fingerprint minutiae template to be constructed. An enrollment process gathers multiple fingerprint images, creates fingerprint minutiae templates corresponding to the acquired fingerprint images, and stores the templates and other data associated with the respective individual or the enrolled fingerprint in a fingerprint database. In an identification process, an unknown raw fingerprint image is obtained via a fingerprint scanner and processed similarly to the enrollment process such that the fingerprint minutiae template of the unknown fingerprint is compared to one or more previously enrolled fingerprint minutiae templates. The identity of the individual associated with the unknown fingerprint is thereby ascertained. In addition, live finger detection can be accomplished in conjunction with the verification or identification process through analysis of the fingerprint image thus enhancing the security of the overall system.

摘要： Apparatuses, systems, and techniques are disclosed for rapidly identifying potential candidates within a pool of enrolled fingerprint images for unconstrained fingerprint matching with an inquiry fingerprint. The techniques may include applying one or more window regions to both enrolled and inquiry fingerprint images and determining a minutiae score for each such window region based on the minutiae within that window region. One or more components of the minutiae score for window regions of the inquiry image may then be compared against similar components in the minutiae scores for window regions of the enrolled fingerprint images, and enrolled fingerprint images having window regions with minutiae scores sufficiently similar to the minutiae score of a window region of the inquiry fingerprint image may be selected for later unconstrained matching with the inquiry fingerprint image.

摘要： A non-parametric computer implemented system and method for creating a two dimensional interpretation of a three dimensional biometric representation. The method comprises: obtaining with a camera a three dimensional (3D) representation of a biological feature; determining a region of interest in the 3D representation; selecting an invariant property for the 3D region of interest; identifying a plurality of minutiae in the 3D representation; mapping a nodal mesh to the plurality of minutiae; projecting the nodal mesh of the 3D representation onto a 2D plane; and mapping the plurality of minutiae onto the 2D representation of the nodal mesh. The 2D representation of the plurality of minutiae has a property corresponding to the invariant property in the 3D representation; and the value of the corresponding property in the 2D projection matches the invariant property in the 3D representation.
