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: The present disclosure provides a method of generating an alert. The method comprises detecting, in an image frame, a unique parameter of an object using object recognition software; determining whether the detected unique parameter is associated with an object of interest; in response to determining that the detected unique parameter is associated with the object of interest, determining whether the associated object of interest has been detected within a deduplication period; in response to determining that the associated object of interest has been detected within the deduplication period, determining a detection score associated with the detected unique parameter; determining whether the detection score exceeds a minimal escalation threshold; and in response to determining that the detection score exceeding the minimal escalation threshold, generating an alert within the deduplication period.

Abstract: 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.
