We propose several very fast algorithms to restore jittered digital video frames (their rows are shifted) in one iteration. The restored row shifts minimize non-smooth and possibly non-convex local criteria applied on the second-order differences between consecutive rows. We introduce specific error measures to assess the quality of dejittering. Our algorithms are designed for gray-value, color and noisy images. Some of them can be considered as parameter-free. They outperform by far the existing algorithms both in quality and in speed. They are a crucial step towards real-time dejittering of digital video.
