The results for a 220-band Indian Pines test site of the AVIRIS database. (a) The original high-resolution data at band 70, (b) low-resolution image of (a) (downsampled in the spatial domain by a factor of three), (c) bicubic interpolation (PSNR = 19.97, SSIM = 0.550082, FSIM = 0.5822), (d) super-resolution by endmember-based TV model (PSNR = 20.30, SSIM = 0.666734, FSIM = 0.6230), (e) super-resolution by the proposed algorithm using the first dictionary (PSNR = 23.17, SSIM = 0.760108, FSIM = 0.6730), (f) super-resolution by the proposed algorithm using the second dictionary (PSNR = 23.19, SSIM = 0.760148, FSIM = 0.6737).
