Paper ID 114

The file contains:

1. Proof for X4 SR kernel extraction (line 196 in the paper) - Link

2. 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.
