Abstract: A monitoring apparatus (102) includes a detection unit (103) that detects a person P taking a predetermined action, based on an image being acquired by imaging an inspection area R, and an output unit (104) that outputs detection information relating to the person P being detected. For example, the predetermined action includes at least one of a first action being decided in relation to an item, a second action being decided in relation to a visual line of a person, a third action being decided in relation to a movement (including staying) of a person, a fourth action being decided in relation to entry in/exit from a predetermined area, and the like.

Abstract: The present invention of an image processing apparatus (10) detects a keypoint of a human body included in an image; computes a degree of similarity between a pose or a movement of a human body detected from the image and a pose or a movement of a human body indicated by a preregistered template image; determines a place in the image where a human body also with the degree of similarity to a pose or a movement of a human body indicated by any template image to be less than a first threshold value is captured; and outputs information indicating the determined place or a partial image acquired by cutting the determined place out of the image.

Abstract: A query acquisition unit (610) acquires a query video. A query frame selection unit (620) selects a plurality of query frames from among a plurality of first frame images included in the query video. A video selection unit (630) selects a video by using the plurality of query frames. At this time, the video selection unit (630) uses references (1) and (2) below as a condition for selecting the video.
Reference (1) A condition that a “similar frame image whose degree of similarity to a query frame satisfies a first reference is present” is satisfied for at least two query frames.
Reference (2) When query frames associated with each of at least two similar frame images are arranged in the same order as that of the at least two similar frame images, the arrangement order coincides with an arrangement order of at least two query frames in a query video.
