Abstract: A computer-implemented method of registering image data in the context of a biometric security system includes receiving an indication of image data, detecting a first point set and a second point set, based on the image data, and generating a metric of closeness between the first point set and the second point set. In addition, the computer-implemented method includes applying the metric of closeness to a transformation model to obtain a transformation parameter and transforming the first point set with respect to the second point set, based on the transformation parameter. Further, the computer-implemented method includes determining whether transformation of the first point set with respect to the second point set indicates convergence and, if so, generating an output indicative of an aligned point set.

Abstract: A system for comparing a biometric sample against a biometric dataset is provided. In one embodiment, a system for comparing a biometric sample against a biometric dataset comprises a database storing at least one biometric dataset. The system may also comprise a comparison module configured to iteratively provide a comparison score for each record in the biometric dataset, wherein the comparison score indicates a likelihood of match between an individual record in the biometric dataset and the biometric sample; wherein, during each iteration. The steps in the iteration may comprise retrieving a model of each of the plurality of records. The steps in the iteration may also comprise comparing the model of each of the plurality of records against the biometric sample. The steps in the iteration may also comprise generating the comparison score for each of the plurality of records. The steps in the iteration may also comprise iteratively compare the biometric sample against a plurality of records.
