Calibration-Free Rolling Shutter Removal
Abstract: We present a novel algorithm for efficient removal of
rolling shutter distortions in uncalibrated streaming videos. Our proposed method is
calibration free as it does not need any knowledge of the camera used, nor does it
require calibration using specially recorded calibration sequences. Our algorithm can
perform rolling shutter removal under varying focal lengths, as in videos from CMOS
cameras equipped with an optical zoom. We evaluate our approach across a broad range of
cameras and video sequences demonstrating robustness, scaleability, and repeatability.
We also conducted a user study, which demonstrates preference for the output of our
algorithm over other state-of-the art methods. Our algorithm is computationally
efficient, easy to parallelize, and robust to challenging artifacts introduced by
various cameras with differing technologies.
