REGION BASED MOVING IMAGE EDITING SYSTEM AND METHOD

One embodiment uses a computer system to define areas with moving image information of interest in a sequence of digital moving image frames. The sequence of digital moving image frames has at least three frames, a first frame, a second frame and a third frame, in time sequence. A set of points identifies the areas with moving image information of interest on the first frame. In the third frame, the areas with moving image information of interest are identified with the set of points. Each point in the set of points has an explicitly defined location in the first frame and an explicitly defined location in the third frame. The location of each point in the first frame corresponds to the same areas with moving image information of interest as each point's location in the second and third frames. For example if one of the points is located at the tip of a runner's left toe in the first frame, then that point will be located at the tip of the runner's left toe in both the second and third frames. The computer system automatically computes the location of the areas of interest in the second frame.
