Abstract:
The method comprises capturing a plurality of images of a single biometric object during a single activation of a biometric sensor and ranking the images based on a ranking metric value of each of the images to determine a highest ranked image and at least one non-highest ranked image. The method comprises comparing, in a first matching attempt for the biometric object, the highest ranked image to templates of a plurality of pre-stored biometric object templates, wherein a matching metric is determined for each compared template, and generating a match indicating signal when it is determined that at least one of the matching metrics exceeds a matching threshold value. When it is determined that none of the matching metrics exceed the matching threshold value, one of the non-highest ranked images is compared, in a further matching attempt, to templates of the plurality of templates based on the matching metrics.
