Abstract
A method of full-frame video stabilization with a polyline-fitted camcorder path is disclosed. The regions was first considered of interest in the video to estimate which regions or objects the user wants to capture, and then use a polyline to estimate a new stable camcorder motion path while avoiding the user's interested regions or objects being cut out. Then, the dynamic and static missing areas caused by frame alignment from other frames were filled to keep the same resolution and quality as the original video. Furthermore, the discontinuous regions were smoothed by using a three-dimensional Poisson-based method. After the above automatic operations, a full-frame stabilized video could be achieved and the important regions and objects could also be preserved.
