Video stabilization and rolling shutter distortion reduction

This paper presents an algorithm that stabilizes video and reduces rolling shutter distortions using a six-parameter affine model that explicitly contains parameters for translation, rotation, scaling, and skew to describe transformations between frames. Rolling shutter distortions, including wobble, skew and vertical scaling distortions, together with both translational and rotational jitter are corrected by estimating the parameters of the model and performing compensating transformations based on those estimates. The results show the benefits of the proposed algorithm quantified by the Interframe Transformation Fidelity (ITF) metric.
