Abstract
A method for matching biometric data is disclosed. A biometric information source is sensed to provide an image thereof. The image is then analyzed to extract features therefrom. A feature is selected as a first feature and a plurality of polygons are generated with a location of the first feature as a vertex of each. The polygons are then used to search a lookup table in order to determine an orientation and translation of the image relative to stored reference data.
