Original Abstract

This paper presents generalization of the Total Variation Primal - Dual reguralitazion method (TV PD) which is applied to the solution of the inverse problem of the linear circuits. Terminals of a multipole resistive passive network are supplied by suitable current sources and voltage of these terminals is measured. Supposing that the structure of the network is known, the conductances of all elements of the network are evaluated by the Electrical Impedance Tomography (EIT) method from the measured voltages. As the classical deterministic inverse method exploiting the minimization of the objective function Least Mean Square is ill conditioned, the above mentioned new regularization term is added. New generalized integral of the multiple-valued Dirac delta function is introduced to evaluate the regularization term.
