Abstract:
1. An object recognition system for recognizing a category of an object based on an image of the object, comprising: a partial feature amount acquisition device which acquires a feature amount of a partial region of the image; a partial recognition device which recognizes the category in the partial region and obtains a partial recognition score; an occurrence probability calculation device which calculates an estimated value of an occurrence probability of the partial recognition score under a condition of being a recognition object category; a total score calculation device which calculates a total score based on nonoccurrence probabilities of the partial recognition scores of a plurality of the partial regions under the condition of being the recognition object category; and a result judgment device which judges the category of the object based on the total score, wherein the total score calculation device calculates the total score according to a numerical formula including a sum total of logarithms of the nonoccurrence probabilities of the partial recognition scores.
