High-Pixel-Resolution Reconstruction Beyond the Measurement-Pixel-Resolution Grid

Caption

Reconstruction results of (a) binary "UESTC" and (b) grayscale "bird" images under 64 × 64 measurements with the sampling rate of SR = 100%. The measurement-pixel-resolution (MPR) and high-pixel-resolution (HPR) reconstructions with scaling factors of α = 2 and α = 4 are presented. ARSPI is compared with CSSPI and PDSPI, as well as their super-resolution-enhanced results using bicubic interpolation and zero-shot super-resolution (ZSSR) method. PSNR, SSIM, and LPIPS values are reported for quantitative evaluation. Zoomed-in views highlight selected fine structures.
