From: Hyperspectral imagery super-resolution by sparse representation and spectral regularization
The results for a 118-band indoor hyperspectral 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 3), (c) bicubic interpolation (PSNR = 12.10, SSIM = 0.343364, FSIM = 0.4745), (d) super-resolution by endmember-based TV model (PSNR = 13.30, SSIM = 0.366734, FSIM = 0.5822), (e) super-resolution by proposed algorithm (PSNR = 16.61, SSIM = 0.393864, FSIM = 0.6433).
