Abstract
An image identification apparatus includes following components. A first generative model creation unit extracts feature information from identification-target images which belong to an identification-target category, and creates a first generative model on the basis of the feature information. A classification unit applies the first generative model to each not-identification-target image which belongs to a not-identification-target category so as to determine a probability of the not-identification-target image belonging to the identification-target category, and classifies the not-identification-target image to a corresponding one of not-identification-target groups in accordance with the probability. A second generative model creation unit that extracts feature information from not-identification-target images which belong to a corresponding one of the not-identification-target groups, and creates a second generative model of each not-identification-target group on the basis of the corresponding feature information.
