Abstract: A causal interaction detection apparatus (2000) extracts pose information for each of persons detected from a video data. The pose information indicates poses of the person in time series. The causal interaction detection apparatus (2000) generates, for each of the persons, a change model that shows change in pose over time based on the pose information. The causal interaction detection apparatus (2000) determines, for each of one or more sets of a plurality of the persons, whether times of changes in pose of the persons in the set correlate with each other. The causal interaction detection apparatus (2000) detects the persons whose times of changes in pose are determined to correlate with each other, as the persons having a causal relationship with each other.

Abstract: An event detecting apparatus acquires one or more video data, and generates, from the one or more video data, object relationship information that indicates two or more action-related relationships between objects. The event detecting apparatus acquires an event information that indicates an event of interest by a sequence of action-related situations at least one of which represents a situation in which a specific action is taken by a specific subject. The event detecting apparatus determines whether or not the event of interest occurs based on the object relationship information and the event information.

Abstract: A lighting management apparatus (101) includes a first acquisition unit (111), and a signal generation unit (112). The first acquisition unit (111) acquires analysis information based on a result being estimated by using an analysis of an image being acquired by photographing a target area TA. The analysis information includes a pose of a person P present in the target area TA. The signal generation unit (112) generates a control signal for controlling one or a plurality of pieces of lighting equipment LE being associated with the target area TA, by using the analysis information and a usage purpose of the target area TA.

Abstract: A control apparatus (103) includes a detection unit (104), and a control unit (105). The detection unit (104) detects a predetermined first gesture by processing image information. When an input condition being a condition for allowing control of a device (102) using the first gesture is satisfied, the control unit (105) controls the device (102) according to the first gesture.

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.
