Image recognition apparatus, image recognition method, and program

摘要

An image recognition apparatus includes an extraction unit configured to extract a feature quantity for each local area from an input image, a conversion unit configured to convert the feature quantity extracted by the extraction unit into a feature quantity indicating a degree with respect to an attribute for each local area, a verification unit configured to verify the feature quantity converted by the conversion unit against a feature quantity of a registered image, and an identification unit configured to identify whether the input image is identical to the registered image by integrating the verification result for each local area acquired by the verification unit.

主权项

1. An image recognition apparatus comprising:
an extractor that extracts a feature quantity for each local area from an input image; a converter that converts the feature quantity for each local area extracted by the extractor into a feature quantity representing respective degrees of similarities with a plurality of representative patterns; a verifier that verifies the feature quantity for each local area converted by the convertor against a feature quantity of a registered image, the feature quantity of the registered image representing respective degrees of similarities with the plurality of representative patterns; and an identifier that identifies whether the input image is identical to the registered image by integrating verification results for a plurality of local areas acquired by the verification unit.
