Abstract: A method and apparatus for tracking objects within a video frame sequence. In one embodiment, a method for tracking an object within a video frame sequence is disclosed. The method includes processing each jth frame of the video frame sequence to determine a motion vector defining motion between a prior jth frame and a current jth frame. The method includes creating an object descriptor for an object being tracked followed by generating a document object model comprising motion information and the object descriptor.

Abstract: A trapping technique that accepts a Postscript or other page description language (PDL) file and outputs a file in PDL format having the correct traps. The input page is first divided into subportions, or tiles, and the tiles are individually processed by evaluating the input file in a corresponding dipping window. Each tile is then analyzed to determine the presence of boundaries or intersections between page objects or color regions. A trapping analyzer generates trap vectors in accordance with a set of desired trapping rules which take into account existing traps and the proximity of other page objects. In a preferred embodiment, the trap vectors are then convened to PDL form.
