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 50% data missing. (b) Image (a) reconstructed by CS-recovery
[62] (PSNR =
19.46). (c) Regularly sampled image with 50% data missing. (d) Image (c)
reconstructed by CS-recovery [62] (PSNR = 19.01). (e) Image (c) reconstructed by
Bicubic (PSNR = 17.77). (f) Image (c) reconstructed by Tikhonov
[63] (PSNR =
22.23). (g) Image (c) reconstructed by BM3D [64] +Bicubic (PSNR = 23.26).
(h) Image (c) reconstructed by ScSR (PSNR = 22.11). (i) Image (c)
reconstructed by 2-D-SBSDI-nomap (PSNR = 23.05). (j) Image (c)
reconstructed by 2-D-SBSDI (PSNR = 23.96). (k) Image (c) reconstructed
by SBSDI (PSNR = 24.56). (l) Registered and averaged image which was
acquired 80 times slower than the image in (i)–(k).
