Kind Code:
A1
Abstract:
Provided is an identification dictionary learning system and the like that create a dictionary which is used in identification and with which a high identification rate can be obtained, in order to detect a prescribed object for which there is a large apparent amount of variation in an image. This identification dictionary learning system (200) is equipped with: a setting unit (211), which receives priorities for a classification comprising a first class and a second class that includes subclasses, and which sets those priorities; an identifier learning unit (213) which, for each combination of subclasses, learns multiple identifiers on the basis of the priorities; a selection unit (215), which selects the combination of subclasses for which a prescribed optimization index for an identifier is optimal; and a weight updating unit (216), which updates a weight on the basis of an identification precision by means of the identifier learned with the selected combination.
