FEATURE AMOUNT GENERATION DEVICE, FEATURE AMOUNT GENERATING METHOD, AND INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD

摘要

A feature amount generation unit 26a of an information processing unit 20-1 generates a feature amount indicating the relationship in spectral reflectance between two points, from spectral data of a multispectral image in an irradiation region of a common light source acquired by a multispectral camera 10. A recognition processing unit 27 performs recognition processing on a subject, on the basis of the feature amount generated by the feature amount generation unit 26a, with at least one of the two points regarded as a position in an image area of the subject that is a recognition target in the multispectral image. Therefore, the feature amount generation unit 26a can easily generate the feature amount robust against variation of the light source and appropriate for the subject. In addition, the authentication processing unit 27 can accurately perform the recognition processing even if the light source varies between registration of the subject and the recognition of the subject.
