Plots of Q value versus the number of measurements based on different reconstruction methods, based on the results obtained in Fig. 7. Curves in panels (a) and (b) are the reconstruction results of “palm” and “aircraft”, respectively. Solid curves and dashed curves with pentagrams show the performance of MDGI with Φ mask − 5 1000 and MDGI1 with Φ mask N , respectively. Solid curves with rounds and triangles correspond to the DGI and NGI reconstruction result, respectively. Curve with squares indicates the GI reconstruction results.
