Real-time video stabilization based on smoothing feature trajectories

In this paper, a real-time video stabilization algorithm based on smoothing feature trajectories is proposed. For each input frame, our approach generates multiple feature trajectories by performing inter-frame template match and optical flow. A Kalman filter is then performed to smooth these feature trajectories. Finally, at the stage of image composition, the motion consistency of the feature trajectory is considered for achieving a visually plausible stabilized video. The proposed method can offer real-time video stabilization and it's removed the delays for caching coming images. Experiments show that our approach can offer real-time stabilizing for videos with various complicated scenes.
