Total variation regularization with reduced basis in electrical impedance tomography
A. Hannukainen, N. Hyvönen, V. Toresen
This work considers using reduced basis techniques in connection to (smoothened) total variation regularization in electrical impedance tomography, but analogous ideas can also be…
