Patent Images

1. A system that facilitates a user interface, comprising:

  • memory;

    a tracking component configured to detect a first object within a scene and tracks the first object, detection of the first object based at least in part upon image comparison of a plurality of images relative to a course mapping of the images;

    a seeding component configured to iteratively seed the tracking component with a set of object hypotheses based at least in part upon a presence of the first object and the image comparison; and

    a filtering component configured to selectively remove a first object hypothesis from consideration based at least in part on a determination that the first object hypothesis has moved within a threshold distance of an other object hypothesis, the filtering component further configured to remove a second object hypothesis from consideration based at least in part on a motion threshold associated with an average movement over a window of time, wherein the second object hypothesis is removed from consideration when a duration of a pause in motion associated with the second object hypothesis exceeds an average time parameter.
