Relationships between the number of measurements and Q value for reconstructed binary image “double-slit” under different GI methods. Inset indicates the comparison between MDGI based on the same mask1 Φ mask − 5 1000 and that based on the varying mask2 Φ mask − 5 N under different measurements. Solid curve with pentagrams shows MDGI reconstruction results. Solid curve with circles and solid curve with triangles correspond to DGI and NGI reconstruction results, respectively. Curve with squares refers to GI reconstruction results.
