Results depict how our proposed algorithm outperforms the gradient-descent simultaneous and project out algorithms in nearly all cases. For large initial RM-S-PE of (a) 10 pixels and (b) 7.5 pixels our approach has clearly better convergence properties than the gradient-descent methods. For a smaller initial RMS-PE of (c) 5 pixels our method performs similarly to the simultaneous approach, with the simultaneous approach exhibiting slightly better convergence performance.
