“…In recent years videos acquired by cameras mounted on a small UAV, with timeliness and flexibility, have got wide application prospects in tactical reconnaissance, surveillance and many other applications [1] [2] . However, due to the complexity of UAV wobble and impacts of surroundings, the videos are always unstable, leading to the airborne video streams with wobbly and shaking motions, disorienting rotations, noisy and other unwanted movements, which often cause the observer feeling vertigo and visual fatigue, even misjudgment.…”

“…However, all these feature based methods have reported a drawback when the input video frames are severely blurred. In the motion smoothing stage techniques like motion vector integration [10,11], frame position smoothing [12], Gaussian filtering [13], Kalman filtering [14], and extended Kalman filtering [15] have been used to separate out the desired motion from the undesired motion. In practice, the stabilized video images often do not overlap perfectly with the boundary of the desired image frame due to motion compensation operation and as a result missing regions are formed along with impairment in resolution.…”

“…In [4], global motion estimation using local motion vectors of subimages obtained by block-matching has been presented. Motion estimation based on edge pattern matching has been demonstrated in [5].…”

“…Two main techniques have been proposed, so far, for the stabilization of translational fluctuations: motion vector integration (MVI) [3,4,8] and DFT filtered frame position smoothing (DFT-FPS) [10]. Motion vector integration constitutes a first-order low-pass infinite impulse response (IIR) filter that integrates differential interframe motion vectors to smoothen the global movement trajectory by simple real-time operation.…”
