ABSTRACT:
A method for identifying the limits of an object (10) in a digitized video display (12) having a series of video frames (14). A seed (26) is introduced into an initial object (18a) in an initial frame (14b) and the seed (26) is expanded to define the limits of the initial object (18a). The modified seed (26a) is then superimposed upon a modified object (18b) and a common area (36) is identified. The common area (36) is modified to become yet another iteration of the seed (26) for continuing the operation into yet another frame (14) having a subsequent version of the object (18). The video seed fill over time method (10) proceeds until no common area (36) is identified for a specified number of frames 14.
