Patent ID: 10572737

Abstract:
Suspicious activity detection methods and systems serve to notify persons of suspicious activity, including potential threats. According to one method, a video processing system (VPS) receives video data in real time/near real time from at least one camera. The VPS determines whether received data representing a first set of video frames includes data representing both an image of a person to be notified and one or more predefined patterns. If so, the VPS tracks the person's image and the predefined pattern(s) within the video data, and determines whether data representing a second set of later-in-time video frames includes data representing the person's image. If the second set of frames excludes the person's image, the VPS continues tracking the predefined pattern(s) in data representing a third set of later-in-time video frames and alerts the person if the tracked pattern(s) is positioned suspiciously relative to the person's current or prior position.
