Efficient Video Stabilization with Dual-Tree Complex Wavelet Transform

  title={Efficient Video Stabilization with Dual-Tree Complex Wavelet Transform},
  author={Derek Pang and Huizhong Chen and Sherif A. Halawa},
We present a new efficient video stabilization method based on Dual-Tree Complex Wavelet Transform (DTCWT). Our method relies on three distinctive techniques in achieving robust stabilization. Our first technique makes use of the linear relationship between the phase changes of DT-CWT and the feature displacement in the spatial domain to perform motion estimation. Our second technique involves determining the optimal smoothed camera motion through linear programming. Our last technique…
