Abstract: A search information acquisition unit acquires a plurality of pieces of search pose information generated for each of a plurality of target images and indicate a pose of a person included in the target image. An exclusion information acquisition unit acquires exclusion pose information indicating a pose of a person included in an exclusion query image. The exclusion query image is an image to be a query of an image needed to be excluded from a search result, and includes at least a person. An exclusion score computation unit computes an exclusion score for each of the plurality of pieces of search pose information. The exclusion score indicates a degree of similarity of the search pose information to the exclusion pose information. An exclusion image selection unit selects, from the plurality of target images by using the exclusion score, an image needed to be excluded from a search result.

Abstract: A query acquisition unit (610) acquires a plurality of pieces of query information. The query information is information generated for each of a plurality of query images, and indicates a feature of the query image. A similar image selection unit (620) selects, as a similar image by using the plurality of pieces of query information, an image whose degree of similarity to at least one of the query images satisfies a reference. A display control unit (630) displays the similar image selected by the similar image selection unit (620) on a display unit. When the similar image selection unit (620) selects a plurality of the similar images, the display control unit (630) sets a display position or a display order of each of the plurality of similar images on the display unit by using the number of the query images in which the similar image satisfies a reference.

Abstract: A query acquisition unit (610) acquires pose information (hereinafter, described as query pose information) that is information to be a query and indicates a pose of a person. A search information acquisition unit (620) acquires a plurality of pieces of search pose information. The search pose information is pose information about an image (hereinafter, described as a target image) to be a search target, and is stored in a database by a plurality of target images. A selection unit (630) selects, from among the plurality of pieces of search pose information, two or more pieces of the search pose information whose degree of similarity to the query pose information satisfies a reference. The selection processing becomes substantially processing of selecting a target image similar to an image (hereinafter, described as a query image) associated with the query pose information.
