Abstract: An information processing apparatus (2000) includes a detection unit (2020), a state estimation unit (2040), and a height estimation unit (2080). The detection unit (2020) detects a target person from a video frame. The state estimation unit (2040) estimates a state of the detected target person. The height estimation unit (2080) estimates a height of the person on the basis of a height of the target person in the video frame in a case where the estimated state satisfies a predetermined condition.

Abstract: An evaluation apparatus (10) includes an acquisition unit (110), an index computation unit (120), and a suitability computation unit (140). The acquisition unit (110) acquires arrangement information and environmental information. The arrangement information indicates at least any of position, orientation and field angle of an image capturing apparatus. The environmental information indicates an environment of a target region. The index computation unit (120) computes a surveillance index by using the arrangement information and the environmental information, the surveillance index indicating difficulty or easiness of surveilling a target object. The suitability computation unit (140) computes suitability of arrangement of the image capturing apparatus indicated by the arrangement information, based on the distribution of the surveillance index in the target region.

Abstract: An information processing apparatus (2000) includes a first analyzing unit (2020), a second analyzing unit (2040), and an estimating unit (2060). The first analyzing unit (2020) calculates a flow of a crowd in a capturing range of a fixed camera (10) using a first surveillance image (12). The second analyzing unit (2040) calculates a distribution of an attribute of objects in a capturing range of a moving camera (20) using a second surveillance image (22). The estimating unit (2060) estimates an attribute distribution for a range that is not included in the capturing range of the moving camera (20).
