Biometric information processing device, biometric-information processing method, and computer-readable storage medium
Abstract:
An biometric-information processing device includes a biometric-information acquiring unit that generates a biometric image representing biometric information on a surface of a specific portion of a user; a divider that divides the biometric image into multiple blocks; a prior-complexity-degree estimator that estimates, for each of the multiple blocks, a prior complexity degree indicating complexity of a pattern of part included in the biometric information and represented in the block, on a basis of a difference between a direction of the pattern of the part included in the biometric information and represented in the block and a direction of a pattern of other part included in the biometric information and represented in the block adjacent to that block; a posterity-complexity-degree determiner that determines, for each of the multiple blocks, a posterior complexity degree indicating complexity of an image of the part included in the biometric information and represented in the block.
