Abstract:
Image reconstruction is a typical pathological problem in the Electrical Capacitance Tomography(ECT): it is a non-linear process.Tikhonov regularization is one of the effective ways to solve the problem.However,the reconstructed image is not as ideal as expected,because the over-smoothing phenomenon of the standard Tikhonov functional leads to some loss of information details in the constructed images.In this paper,based on the standard Tikhonov algorithm,a new iterated operator is proposed.Through this ope...
