Rolling shutter distortion removal based on curve interpolation

In videos shot by rolling shutter cameras, rapid camera or object motion may cause obvious image distortions. This paper proposes a rectification method that removes rolling shutter distortions by performing curve interpolation for each pixel. This method does not require camera calibration, and it can handle camera and object motion simultaneously. The method only assumes that the motion is smooth. If camera motion alone causes distortions, a variation of this method requiring less computation can be used. Experiments on synthetic datasets and real videos show that the methods can remove rolling shutter distortions effectively.
