Video seed fill over time
First Claim
1. A method for identifying an object within a plurality of frames of a moving picture video, comprising:
- identifying the object within a first frame of the video according to a distinguishing characteristic of the object and further identifying a location of the object;
superimposing the location of the object within a second frame of the video;
identifying a common area within the second frame of the video;
expanding the common area to identify the location of a modified object within the second frame of the video;
superimposing the location of the modified object within a third frame of the video;
identifying a second common area within the third flame of the video; and
expanding the common area to identify a second modified object within the third frame of the video.

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.

6. A method for isolating an object through a series of video frames, comprising:
-
a choosing an identifying criterion; b placing a seed within the object in an initial frame; c1 expanding said seed to define the limits of the object according to the identifying criterion; c2 saving the location of the seed; d advancing to a next frame; e superimposing the seed on said next frame; f identifying a common area having both the seed and the identifying criterion; and g modifying the seed to coincide with the common area. - View Dependent Claims (7, 8, 9, 10, 11)

12. An object defining system for defining a portion of a moving picture video image, comprising:
-
display means for displaying a first frame of a computer image; selection means for an operator to place a seed upon the first frame; and a computer program including operations for; a expanding the seed to define an object; b redefining the seed to correspond to the location of the object and saving a location of the seed; c advancing to a next frame; d overlaying the location of the seed on the next frame; e identifying a common area, the common area being any portions of the next frame which are shared by the object and the seed; and f redefining the seed to correspond to the common area. - View Dependent Claims (13, 14, 15, 16, 17, 18)
