Rigid registration results of the real 2D brain MR T1 and MR PD images. Various values of two parameters and were chosen. The transformation parameters were generated randomly from the range 0–10 mm, with the unit of errors also in millimeters. (a) Registration errors for several various values, and = 3000. (b) Results of different numbers of random samples, with .
