A robust video stabilization technique using integral frame projection warping
In this paper, a video stabilization technique based on optimized dynamic time warping (DTW) has been proposed. The method uses integral frame projection warping (IFPW) for the relative motion estimation between consecutive frames. Implementation of DTW is done using dynamic programming, to give a significant reduction in terms of memory and processing time. Most of the motion estimation techniques are adversely affected due to blurring, low intensity and large displacements. The proposed method gives accurate results under these conditions and proves to be a robust for various applications such as moving platform and night shooting, over existing intensity-based motion estimation techniques. Efficiency of the proposed IFPW technique, for dark video and blurry frames, is measured using motion estimation error analysis. Overall performance evaluation of the stabilization system is done using interframe transformation fidelity and processing time.
