Automatic video deshearing for skew sequences capturedby rolling shutter cameras

A novel automatic video deshearing is proposed to reduce the skew artifacts (jelly artifacts) in sequences captured by CMOS censor cameras. The paper first considers the principles of skew artifacts in rolling shutter cameras. Then a deshearing algorithm with high accuracy is discussed with automatic skew artifact detection. A video completion step is also implemented to reconstruct unavailable pixels in the new grid of the desheared frame. Simulation results show that the proposed method effectively reduces the skew artifacts for different sequences captured by rolling shutter cameras.
