Web2 Mar 2016 · Given sigma and the minimal weight epsilon in the filter you can solve for the necessary radius of the filter x: For example if sigma = 1 then the gaussian is greater than epsilon = 0.01 when x <= 2.715 so a filter radius = 3 (width = 2*3 + 1 = 7) is sufficient. sigma = 0.5, x <= 1.48, use radius 2. sigma = 1, x <= 2.715, use radius 3. WebSolving the Kalman smoothing problem. There are many ways to solve the Kalman smoothing problem (4). One method is to eliminate the equality constraint [BV04, x4.2.4] and solve the resulting unconstrained least squares problem, which has a banded coe cient matrix.
