Abstract: To utilize a result of analyzing an interval between persons included in a video, a video analysis apparatus 100 includes an interval acquisition unit 110 and a display control unit 113. The interval acquisition unit 110 acquires an interval between persons included in a video acquired by photographing a target region. The display control unit 113 causes a display unit to display a time-series transition of first information relating to the number of persons with the acquired interval being equal to or less than a reference value.

Abstract: To achieve faster search processing in the search processing of a similar image, based on a feature value of each of a plurality of keypoints of a human body included in an image, the present invention provides an image processing system 10 including: a target image acquisition unit 11 that acquires a target image; a skeleton structure detection unit 12 that performs processing of detecting a keypoint of a human body included in the target image; a first verification unit 13 that extracts a first reference image whose relationship with the target image satisfies a first extraction condition, from among a plurality of reference images, based on the detected keypoint; and a second verification unit 14 that extracts a second reference image whose relationship with the target image satisfies a second extraction condition, from among the first reference images, based on the detected keypoint.
