摘要
Real-time video stabilization for mobile devices based on on-board motion sensing. In accordance with a method embodiment of the present invention, a first image frame from a camera at a first time is accessed. A second image frame from the camera at a subsequent time is accessed. A crop polygon around scene content common to the first image frame and the second image frame is identified. Movement information describing movement of the camera in an interval between the first time and the second time is accessed. The crop polygon is warped to remove motion distortions of the second image frame is warped using the movement information. The warping may include defining a virtual camera that remains static when the movement of the camera is below a movement threshold. The movement information may describe the movement of the camera at each scan line of the second image frame.
