ABSTRACT:
Image data is processed consisting of a first data set representing a polarity of moving objects and a second data set derived from two dimensional video frames. Three dimensional video objects are perceived as moving in three dimensional space in response to a trajectory definition. The trajectories of the moving objects is modified in response to the position of the two dimensional video frames. The modification may be affected in response to a matte or key signal derived from the video images, allowing the foreground video image to be combined with three dimensional moving particles.
