Algorithm 1.

Registration scheme

1:	Get the number of rejection steps n_R from user
2:	Get the fraction of total blocks rejected f_R from user
3:	for i = 0 to n_R do
4:	F_i ⇐ KU_i
5:	U_i₊₁ ⇐ [K + H^T SH]⁻¹ [H^T SD + F_i]
6:	for all Blocks k do
7:	Compute error function ξ_k
8:	end for
9:	Reject $\frac{f_{R}}{n_{R}}$ blocks with highest error function ξ
10:	Recompute S, H, D
11:	end for
12:	repeat
13:	F_i ⇐ KU_i
14:	U_i₊₁ ⇐ [K + H^TSH]⁻¹ [H^T SD + F_i]
15:	until Convergence
