Two Combined Restriction Regularization Algorithm for Electrical Capacitance Tomography Visualization

Résumé fourni par la source

Based on the restrictions of minimum of gray energy and second order smoothness,the paper presented.an novel regularization method for electrical capacitance tomography by which a regularization matrix was constructed using the combination of an identity matrix and a second order differential operator.The difference between the new algorithm and the common regularization ones is that the regularization levels related to the site of the pixels vary spatially to achieve the consistently smoothing effects in different sites of the region imaged.Simulation experimentations have been performed to verify that the new algorithm is capable of reconstructing superior image quality over the standard Tikhonov algorithm.
