Claim One:
1. A finger biometric sensor comprising: an array of finger biometric sensing pixels; and processing circuitry coupled to the array of finger biometric sensing pixels and configured to collect an initial plurality of enrollment finger biometric data sets, generate an initial enrollment template based upon the initial plurality of finger biometric data sets, and generate an initial enrollment criteria indicative of a quality of the initial enrollment template and based upon at least one characteristic of the initial enrollment template, the initial enrollment criteria being generated based upon a total number of nodes of the initial enrollment template representing enrollment images from the initial plurality of finger biometric data sets and a total number of edges of the initial enrollment template representing alignment information of the initial plurality of finger biometric data sets between pairs of the enrollment images, collect at least one additional enrollment finger biometric data set, generate an additional enrollment template based upon the at least one additional enrollment finger biometric data set, and adapt the initial enrollment criteria based on the additional enrollment template to define an additional enrollment criteria indicative of a quality of the initial enrollment template and the additional enrollment template, and based upon at least one characteristic of the additional enrollment template, flag the initial enrollment template and the additional enrollment template as sufficient if the additional enrollment criteria meets an acceptance condition, and collect further enrollment finger biometric data and adapt the additional enrollment criteria if the additional enrollment criteria fails to meet the acceptance condition.
