    Abstract: A query acquisition unit (109) acquires a first query moving image having a plurality of time-series first frame images and at least one second query moving image having a plurality of time-series second frame images. A feature value computing unit (103) computes a feature value of a keypoint detected from an object being included in each of the first frame images and the second frame images. A correspondence relationship determination unit (114) determines a second frame image associated with each of the plurality of first frame images. An integration unit (113) performs, for a plurality of combinations of the first frame image and the second frame image associated with each other, processing of integrating the feature values computed from each of the first frame image and the second frame image, and thereby generates an integrated query in which the integrated feature values are arranged in time series.

    Abstract: An image selection apparatus includes a query acquisition unit (610) and an image selection unit (620). The query acquisition unit (610) acquires query information indicating a pose of a person. The query information includes relative positions of a plurality of keypoints indicating different portions of a human body from each other. The image selection unit (620) selects at least one target image from a plurality of images subject to selection by using the query information. Specifically, the image selection unit (620) determines weighting for at least one of the keypoints by using a difference between reference pose information indicating reference relative positions of the plurality of keypoints and the query information. Then, the image selection unit (620) selects a target image by using relative positions of the plurality of keypoints of a person included in the image subject to selection, the query information, and the weighting.

    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.
