Abstract: A query acquisition unit (610) acquires query information. The query information includes information indicating a relative position of each of a plurality of keypoints. By using the query information and reference pose information, a threshold value setting unit (620) sets a threshold value for selecting at least one target image from a plurality of selection target images. An image selection unit (630) selects at least one target image from the plurality of selection target images. Specifically, the image selection unit (630) selects at least one target image by using relative positions of a plurality of keypoints of a person included in each of the plurality of selection target images, the query information, and the threshold value. The threshold value setting unit (620) may set a threshold value for classifying a plurality of selection target images.

Abstract: A search unit (105) of an image selection apparatus (10) 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 image selection unit (620) selects at least one target image from a plurality of images subject to selection by using the query information. Herein, the query information includes relative positions of a plurality of keypoints indicating different portions of a human body from each other. Then, the image selection unit (620) selects the at least one target image by using a relative position of the keypoint of a person included in the image subject to selection, at least one of a kind of a lacking keypoint and a number of lacking keypoints, and the query information, the lacking keypoint being the keypoint that lacks in the person.

The method comprising applying a slurry for a first layer to a surface of a current collector, applying a slurry for a second layer to the slurry for the first layer before the slurry for the first layer is dried, and drying the slurries for the first layer and the second layer after applying the slurries for the first layer and the second layer to obtain a laminated structure in which the first layer and the second layer are laminated in this order on the current collector. A first binder or thickener for the slurry for the first layer and a second binder or thickener for the slurry for the second layer are selected such that when viscosities are measured for a first solution including solvent and the first binder or thickener dissolved in the solvent in a specific mass ration and a second solution including a solvent and the second binder or thickener dissolved in the solvent at the same mass ration as the mass ration of the first binder or thickener under the same conditions, the viscosity of the first solution is higher than the viscosity of the second solution.
