Title: SYSTEMS AND METHODS FOR DETECTING AND TRACKING MOVABLE OBJECTS
Abstract:
Systems, methods and devices are provided herein for detecting and tracking one or more movable objects. A method for supporting visual tracking may be provided. The method may comprise: receiving a plurality of image frames (112-1,112-2) captured at different times (T1,T2) using an imaging device (110), wherein each image frame comprises a plurality of pixels that are associated with a plurality of feature points; analyzing the plurality of image frames (112-1,112-2) to compute movement characteristics of the plurality of feature points; and identifying at least one tracking feature (216) relative to at least one background feature (214) based on the movement characteristics of the plurality of feature points.
