Two types of sampling patterns and their reconstruction results by CS-recovery [62], Bicubic, Tikhonov [63], BM3D [64]+Bicubic, ScSR [32], 2-D-SBSDI-nomap, 2-D-SBSDI, and our SBSDI method. (a) Randomly sampled image with 75% data missing. (b) Image (a) reconstructed by CS-recovery [62] (PSNR = 20.83). (c) Regularly sampled image with 75% data missing. (d) Image (c) reconstructed by CS-recovery [62] (PSNR = 20.67). (e) Image (c) reconstructed by Bicubic (PSNR = 17.75). (f) Image (c) reconstructed by Tikhonov [63] (PSNR = 22.68). (g) Image (c) reconstructed by BM3D [64] +Bicubic (PSNR = 23.28). (h) Image (c) reconstructed by ScSR (PSNR = 23.09). (i) Image (c) reconstructed by 2-D-SBSDI-nomap (PSNR = 23.68). (j) Image (c) reconstructed by 2-D-SBSDI (PSNR = 23.99). (k) Image (c) reconstructed by SBSDI (PSNR = 24.58). (l) Registered and averaged image which was acquired 160 times slower than the image in (i)–(k).
