Blind Super-Resolution Methods comparison

We compare ground truth kernel, Michaeli & Irani, 2013 and our KernelGAN. PSNR of ZSSR, when supplied with those kernels, is noted, emphasizes the significance of kernel accuracy.

Blind Super-Resolution Methods comparison

Visual comparison of our method (KernelGAN + ZSSR[30]) to SotA SR and Blind-SR methods: RCAN+ [38], EDSR+ [21], PDN [34], WDSR [36], Michaeli & Irani [24] + ZSSR[30], and Bicubic interpolation. Both on images from DIV2KRK and "real images" downloaded from the internet
