Abstract
A method for supporting visual tracking includes receiving a plurality of image frames captured at different times using an imaging device. Each of the plurality of image frames includes a plurality of pixels associated with a plurality of feature points. The method further includes analyzing the plurality of image frames to compute movement characteristics of the plurality of feature points and identifying a tracking feature relative to a background feature based on the movement characteristics of the plurality of feature points.
