Present disclosure provides a method for determining if an event relates to an unauthorized subject, the method comprising: determining a likelihood of how the event is similar to at least one of: (i) at least one event of a list of events relating to the unauthorized subject and (ii) at least one of a list of events relating to an authorized subject, each event of the list of events comprising data identifying the unauthorized subject, the determination of likelihood being based on the data identifying the unauthorized subject; and determining the event to relate to the unauthorized subject in response to the determination of the likelihood.

Determining if an event relates to an unauthorized subject

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.

Present disclosure provides a method and a server for adaptively updating a target subject identification to be stored in a database, the target subject identification pertaining to a target subject in a system comprising a plurality of servers, the server configured to: receive target subject information; assign a first target subject identification to the target subject information and store the first target subject identification in a first database of the server; and send a request, to the plurality of servers, to synchronize the target subject identification, the request including the target subject information relating to the target subject.

Method and server apparatus for adaptively updating a target subject identification stored in a database

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.

Duration and potential region of interest for suspicious activities

Present disclosure provides a method for managing an event to generate an alert indicating a subject is likely to be unauthorized, the event comprising data identifying the subject, the method comprising: within a pre-determined period based on a timestamp at which the event is stored in a cache, detecting a recall event comprising the data identifying the subject, the recall event indicating the subject is not likely to be unauthorized; and removing the event from the cache in response to detecting the recall event comprising the data identifying the subject within the pre-determined period.

Method, an apparatus and a system for managing an event to generate an alert indicating a subject is likely to be unauthorized

A method and system () for grouping same persons are provided. The system () includes: a database () for storing person specific data of a plurality of reference persons in a hierarchical structure; an input module () for receiving person specific data of a target person; and a similarity search module () for searching the database () for data similar to the person specific data of the target person.

Methods, systems, and non-transitory computer readable medium for grouping same persons

There is provided a method for identifying potential associates of at least one target person, the method comprising: providing a plurality of videos; identifying appearances of the at least one target person in the plurality of videos; establishing a plurality of video scenes from the plurality of videos, wherein each one of the plurality of video scenes begins at a first predetermined duration before a first appearance of the at least one target person in the respective video scene and ends at a second predetermined duration after a last appearance of said at least one target person in the respective video scene; determining individuals who appear in more than a predetermined threshold number of the plurality of video scenes; and identifying the individuals as potential associates of the at least one target person.
