Abstract:
A method, device and system for generating an enrollment template are provided. The enrollment template is generated by collecting a placement image representing a portion of a biometric object such as a fingerprint. The placement image is localized on the fingerprint by comparing the data in the placement image to data in a floor map representing a larger image of the fingerprint obtained by swiping or rolling the fingerprint over a sensing area of a partial placement sensor. As additional placement images are obtained more information is provided for the enrollment template. The additional placement images are also localized to one another utilizing the floor map. The enrollment template is generated based on a grouping of each placement image to its neighboring placement images.
