An image reconstruction algorithm based on total variation with adaptive mesh refinement for ECT
H Wang, L Tang, Z Cao - Flow Measurement and Instrumentation, 2007 - Elsevier
In this paper, a robust image reconstruction algorithm for electrical capacitance tomography
(ECT) is proposed. The key feature of the algorithm is the use of adaptive mesh refinement
based on total variation (TV) in solving the inverse problem. It keeps the edge preserving
and scale-dependent properties of total variation regularization, and enhances the
distinguishability by using adaptive mesh refinement. This strategy improves the spatial
resolution efficiently with less calculation and is less underdetermined than uniform …
