Reconstruction results and evaluation metrics under SNR-based data reduction strategy. (a) gives the distribution of the 48 detectors’ SNR level in a case scenario. (b) plots the computation time and measurements left corresponding to different threshold of SNR. (c) plots the 4 metrics versus different threshold of SNR. (d)-(f) show 3 visual reconstructions with retained measurements after filtering by the specific SNR threshold of 1.99, 2.02, and 2.05, respectively.
