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 captured at different times using an imaging device, wherein each image frame comprises a plurality of pixels that are associated with a plurality of feature points; analyzing the plurality of image frames to compute movement characteristics of the plurality of feature points; and identifying at least one tracking feature relative to at least one background feature based on the movement characteristics of the plurality of feature points.
