Abstract: The method comprising determining a set of coordinates each for two or more appearances of a target subject within a sequence of images, the set of coordinates of the two or more appearances of the target subject defining a first path; determining a set of coordinates each for two or more appearances of a related subject within a sequence of images, the related subject relating to the target subject, the set of coordinates of the two or more appearances of the related subject defining a second path; determining one or more minimum distances between the first path and the second path so as to determine at least a region of interest; determining a timestamp of a first appearance and a timestamp of a last appearance of the target subject; and determining a timestamp of a first appearance and a timestamp of a last appearance of the related subject.

Abstract: Methods, systems and computer readable medium for object detection coverage estimation are provided. The system for object detection coverage estimation includes a camera and a processing means. The processing means is coupled to the camera to receive image data acquired by the camera, the image data including a detected object. The processing means is configured to determine a spatial coverage of the detected object based on detected object metadata associated with the detected object in the image data received from the camera.

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.
