Sparse reconstruction of log-conductivity in current density impedance tomography
Madhu Gupta, Rohit Kumar Mishra, Souvik Roy
A new non-linear optimization approach is proposed for the sparse reconstruction of log-conductivities in current density impedance imaging. This framework comprises of minimizing…
