Abstract: A management apparatus (10) includes a motion detection unit (11), a related image specifying unit (12), a determination unit (13), and an output unit (14). The motion detection unit (11) detects a predetermined motion performed by a person from image data of an image obtained by capturing a predetermined place including the person. The related image specifying unit (12) specifies a predetermined related image related to the safety of the person. The determination unit (13) determination means determines whether or not the person is in a safe situation based on the detected motion and a positional relationship between the person performing the motion and the related image. The output unit (14) outputs determination information including a result of the determination performed by the determination means.

Abstract: An image processing system (10) includes an analysis means (11), a determination means (12), and a label assigning means (13). The analysis means (11) recognizes a plurality of motion images indicating a motion of a person from image data of motion images according to a plurality of consecutive frames obtained by capturing the person who performs a series of motions. The determination means (12) determines whether or not the motion image and a predetermined reference motion are related to each other. The label assigning means (13) assigns a label to at least some of the consecutive frames in the motion image based on the determination.

Abstract: A relationship extracting apparatus acquires event information that indicates features of an event of interest, determine target duration based on one or more features of the event of interest, and extract one or more action-related relationships that exist during the target duration from object relationships information. The object relationship information indicates two or more action-related relationships between objects in association with time at which or during which the action-related relationship exists.

Abstract: An event detection system (10) includes: a calculation unit (16) that calculates a degree of similarity between at least a part of skeletal information extracted from a captured image in which a user who is visiting an ATM is captured and at least a part of registration skeletal information, the registration skeletal information being extracted from a registration image showing a phone call action of a person and being registered in an action database; and a determination unit (17) that determines that an event related to the ATM has been detected when the degree of similarity is equal to or greater than a predetermined threshold. Thus, a problematic event at an ATM can be easily detected while protecting privacy.

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.
