I am working on video stabilization from last few days. I succeeded in stabilizing the video when the degree of shakiness is less. As the frequency of shakiness increases the algorithm fail to work. Can anyone suggest what i am doing wrong.

My algorithm:- 1) Find the transformation from previous to current frame using good feature to track and optical flow for all frames. 2) Accumulate the transformations to get the “trajectory” for x, y, angle, at each frame. 3) Smooth out the trajectory using a sliding average window. 4) Create a new transformation such that new_transformation = transformation + (smoothed_trajectory – trajectory). 5) Apply the new transformation to the video.

Thanks & Regards, Rakshita
