Encoder-Decoder Residual Network (IVIP-Lab)

This repository is our solution for NTIRE2019 Real Super-Resolution Challenge.

We, team IVIP-LAB, won the 9th PSNR and Top5 SSIM in the final phase of NTIRE2019 Real Super-resolution challenge.
Our paper will be published in CVPR 2019 Workshop. </i> [pdf] [poster]
