摘要： 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.

摘要： A feature extraction apparatus, a method, and a program capable of efficiently using processing resources are provided. In a feature extraction apparatus, a feature extraction unit receives an object image and extracts features of an object included in the received object image. The determination unit determines a value of M (the value of M is an integer equal to or larger than one but equal to or smaller than N), which is the number of object images whose features will be extracted of N object images with which the first tracking ID is associated, in accordance with a usage status of processing resources of the feature extraction apparatus.

摘要： 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.
