I have been working on video stabilization for quite a few weeks now. The algorithm I'm following basically involves 3 steps :-
- FAST feature detection and Matching
- Calculating affine transformation (scale + rotation + translation x + translation y ) from matched keypoints
- Smooth motion parameters using cubic spline or b-spline.
I have been able to calculate affine transform. But I am stuck at smoothing motion parameters. I have been unable to evaluate spline function to smooth the three parameters.
Here is a graph for smoothed data points
Any suggestion or help as to how can I code to get a desired result as shown in the graph?
