Abstract: A preliminary image is captured that includes parts of an authentication target person. Main authentication targets are determined. The main authentication targets are those parts that each have an acceptable image-capturing state. A single image-capturing device can then be controlled to successively capture images of the main authentication parts of the authentication target person that have been determined with different settings. These images of the main authentication parts that have been captured can then be output. For instance, authentication of the target person may be performed using authentication data for each main authentication part, where such authentication is successfully when authentication for all the main authentication parts is successful.

Abstract: To utilize a result of image analysis, an image analysis apparatus 100 includes an analysis result acquisition unit 110 and a counting unit 111. The analysis result acquisition unit 110 acquires analysis information being information acquired by analyzing a still image and including an appearance attribute to which a person included in the still image belongs. The counting unit 111 counts, for each appearance attribute, the number of persons belonging to the appearance attribute in the still image by using the analysis information, and generates counting information indicating a result of the counting in units of still images.

Abstract: A retrieval apparatus (2000) is accessible to a storage region (50) in which a plurality of pieces of object information (100) are stored. The object information (100) includes a feature value set (104) being a set of a plurality of feature values acquired regarding an object. The retrieval apparatus (2000) acquires a feature value set (retrieval target set (60)) being a retrieval target, and determines the object information (100) having the feature value set (104) similar to the retrieval target set (60) by comparing the retrieval target set (60) with the feature value set (104). Herein, in a case where a feature value set satisfies a predetermined condition, the retrieval apparatus (2000) performs comparison between the feature value set and another feature value set by using a part of feature values within the feature value set. Further, the retrieval apparatus (2000) outputs output information relating to the determined object information (100).

Abstract: An action localization apparatus acquires a target clip and detects persons from the target clip. The action localization apparatus generates a person clip from the target clip for each of the persons detected from the target clip, and extracts a feature map from each of the person clip. The action localization apparatus computes, for each of predefined action classes, an action score that indicates confidence of an action of that action class being included in the target clip based on the feature maps extracted from the person clips, and localizes each action whose action class has the action score larger than or equal to a threshold by performing class activation mapping on each of the person clips.
