PATTERN PROCESSING DEVICE, METHOD THEREFOR, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To suppress decrease of recognition accuracy and detection accuracy even when a change occurs at a local region.

SOLUTION: This pattern processing device is provided with a reference local region setting unit 1802 which sets a reference local region on the basis of a feature point detection result by a face organ feature point detection unit 101; a variant local region generation unit 1803 which generates a plurality of variant local region patterns with reference to a surrounding image region of the reference local region; a similarity calculation unit 106 for obtaining similarities among the input pattern and the registered pattern of the reference local region and the plurality of variant local region patterns; a representative similarity calculation unit 107 for obtaining a representative similarity from the similarities; and a determination unit 109 which determines a class to which the input pattern belongs on the basis of the representative similarity.
