Synthetic experiments showing that our noise covariance estimation, which assumes that the motions are zero, is also accurate for small nonzero motions. (A) The motion between synthetic frames with noise and slightly translated versions (not shown) are computed over 4,000 runs at the marked point in red for several different translation amounts. Each time, different but independent noise is added to the frames. (B) The sample covariance vs. motion size. (C) Relative error of horizontal variance vs. motion size. (D) Relative error of vertical variance vs. motion size. C and D are on the same color scale.
