Abstract:

The key technology of electronic image stabilization is the motion vector estimation. FPS(Feature points) matching based on the ROI(Region of Interest) area is used to estimate motion vectors. Firstly, ROI of the input image was selected, then the FPS were detected by Harris. Secondly, the rule of SAD inside the
window was used to sparse the FPS and find matching point in the adjacent frame. Finally, distance criterion was applied to eliminate false match points. Results of frame by frame motion compensation show the effectiveness of the algorithm.

Key words: region of interest(ROI), feature window, rule of distance
