System and method for video stabilization
First Claim
1. A method for stabilizing elements within an image sequence formed from a temporal sequence of frames, each frame having an area, the image sequence generated by an image capturing device, the method comprising:
- dividing the area of the frames of the sequence of frames into sub-areas comprising a foreground area portion and background area portion;
selecting a background pixel domain for evaluation from the background area portion of the frames;
evaluating the background pixel domain to generate an evaluation for subsequent stabilization processing calculated between corresponding pairs of a sub-sequence of select frames; and
applying stabilization processing based on the evaluation to the frames of the sequence of frames.

Abstract
Disclosed is a method and circuit for stabilizing unintentional motion within an image sequence generated by an image capturing device (102). The image sequence is formed from a temporal sequence of frames, each frame (202) having an area and an outer boundary. The images are two dimensional arrays of pixels. The area of the frames is divided into a foreground area portion (204) and background area portion (206). From the background area portion of the frames, a background pixel domain is selected for evaluation (404). The background pixel domain is used to generate an evaluation (406), for subsequent stabilization processing (408), calculated between corresponding pairs of a sub-sequence of select frames.
