Comparison of reconstructions using GNC-ADMM and GNC-GN with 8 sources and 8 detectors: (a) and (f) give reconstruction with GNC-ADMM (b) and (g) give reconstruction with GNC-GN. (c) and (h) represent the comparison of 1D cross section images, where the cross line is the same as simulation 1. (d) and (i) give the evolution of \(\mathcal {E}_{l_2}\). (e) and (j) give the evolution of \(\mathcal {E}_{tv}\).
