To solve the selection problem of Tikhonov regularization parameter in electrical capacitance tomography
A method is proposed to get an optimal regularization parameter using Morozov discrepancy principle
which make the (output) error due to regularization equals the error level in the data.To get an optimal regularization parameter rapidly and reasonably
a hybrid algorithm by combining three-order convergence algorithm and two parameter model is proposed.Numerical experimental results show that regularization parameter selection affects both the reconstruction speed and quality;the proposed hybrid algorithm has high image reconstruction speed and high accuracy for different flow patterns.
