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.

The electrode comprises a current collector 110, an active material layer 111 formed on at least one surface of the current collector 110, and an insulating layer 112 formed on the surface of the active material layer 111. The active material layer 111 includes an active material and a first binder. The insulating layer 112 includes non-conductive particles and a second binder. An interfacial binder ratio, which is a ratio of amount of a binder existing in an interface region between the active material layer 111 and the insulating layer 112 per unit thickness of the interface region to amount of a binder existing in the active material layer 111 per unit thickness of the active material layer 111, is 85% or more.
