WitrynaWe have also derived a method to estimate the regularization parameter of a Tikhonov regularized version of the Richardson-Lucy algorithm. These iterative image restoration algorithms need a first estimate to start their iteration. An obvious and frequently used choice for the first estimate is the acquired image.
