Information processing apparatus and control method thereof

摘要

This invention provides a technique which can enhance personal recognition precision in personal recognition processing of a face in an image. To this end, a management unit classifies feature patterns each including feature information of a plurality of parts of a face region of an object extracted from image data, and manages the feature patterns using a dictionary. A segmenting unit determines whether or not feature information of each part of the face region of the object is segmented, and segments the feature information of the part of interest into a plurality of feature information as new feature information. A registration unit registers a feature pattern as a combination of the new feature information of the part of interest and feature information of parts other than the part of interest in the dictionary as a new feature pattern of the object.

主权项

1. An apparatus comprising:
a management unit that classifies feature patterns for identifying an object, where each pattern includes a plurality of feature amounts corresponding to a plurality of parts of a face region of the object extracted from image data, and that manages the feature patterns using a dictionary; a dividing unit that divides a feature amount of a target part among the plurality of parts of an object of interest, into a plurality of division feature amounts as a plurality of new feature amounts of the target part; and a registration unit that registers, in a case where the dividing unit divides the feature amount of the target part into the plurality of new feature amounts, a plurality of new feature patterns for identifying the object of interest, where the plurality of new feature patterns are obtained by combining each of the plurality of new feature amounts of the target part divided by the dividing unit with feature amounts of parts other than the target part, in the dictionary.
