1. A system that facilitates a user interface, comprising: a tracking component that detects at least one of a plurality of objects within a scene and tracks the respective object, detection of the object based at least in palt upon image comparison of a plurality of images relative to a course mapping of the images; a seeding component that iteratively seeds the tracking component with object hypotheses based upon the presence of the object and the image comparison; and a filtering component that selectively removes the tracked object from the object hypotheses and/or at least one object hypothesis from the set of object hypotheses, the tracked object removed based at least in part upon a region-based approach in determining depth to cursors and move windows.
