ABSTRACT:
A video stabilization method. First, optical flows between successive frames are calculated. The camera motion is then estimated by fitting the computed optical flow field to a simplified affine motion model with a trimmed least square method. Then, the computed camera motions are smoothed to reduce the motion vibrations by using a regularization method. Finally, all frames of the video are transformed based on the original and smoothed motions to obtain a stabilized video.
