A dual-parameter regularization method for electrical conductivity imaging

Abstract:

This paper presents a dual-parameter regularization method with two parameters by introducing a regularization term with a second order regularization operator. The optimal value of the regularization parameter is determined by applying the L-curve criterion, discrepancy principle, and generalized cross-validation. The validity and superiority of the proposed method is verified by numerical simulations of the theoretical model with Truncated Singular Value Decomposition, Conjugate Gradient, a...
