Query: A Nonlinear Weighted Total Variation Image Reconstruction Algorithm for
  Electrical Capacitance Tomography   A new iterative image reconstruction algorithm for electrical capacitance
tomography (ECT) is proposed that is based on iterative soft thresholding of a
total variation penalty and adaptive reweighted compressive sensing. This
algorithm encourages sharp changes in the ECT image and overcomes the
disadvantage of the $l_1$ minimization by equipping the total variation with an
adaptive weighting depending on the reconstructed image. Moreover, the
non-linear effect is also partially reduced due to the adoption of an updated
sensitivity matrix. Simulation results show that the proposed algorithm
recovers ECT images more precisely than existing state-of-the-art algorithms
and therefore is suitable for the imaging of multiphase systems in industrial
or medical applications.
