Abstract: A pattern recognition device (10) includes an acquisition unit (13) configured to acquire a plurality of recognition candidates obtained by pattern recognition for an input image and having a recognition score, a calculation unit (17) configured to calculate an evaluation value obtained by quantifying a possibility of a recognition candidate (K) being correct answer data corresponding to the input data on the basis of a feature quantity regarding a recognition candidate (A1) and the recognition candidate (K), for each pair of the recognition candidate (A1) having the number one recognition score and another recognition candidate (K) among the plurality of recognition candidates, and a determination unit (18) configured to determine a final recognition result from among the plurality of recognition candidates on the basis of an evaluation value for each recognition candidate (K).

Abstract: A planogram information generating device includes: an image acquiring unit that acquires an image acquired by imaging product display shelves; a detection unit that detects product area images representing the products from the image of the product display shelves; a product recognizing unit that recognizes products represented by the product area images on the basis of information relating to images of products stored in advance; a determination unit that determines validity of recognition of one product area image as a first product on the basis of relevancy information between the first product recognized as a product represented by the one product area image and one or more second products recognized as products represented by one or more other product area images other than the one product area image; and a correction unit that corrects the first product recognized as the product represented by the one product area image.
