  This paper introduces the real image Super-Resolution (SR) challenge that was
part of the Advances in Image Manipulation (AIM) workshop, held in conjunction
with ECCV 2020. This challenge involves three tracks to super-resolve an input
image for $\times$2, $\times$3 and $\times$4 scaling factors, respectively. The
goal is to attract more attention to realistic image degradation for the SR
task, which is much more complicated and challenging, and contributes to
real-world image super-resolution applications. 452 participants were
registered for three tracks in total, and 24 teams submitted their results.
They gauge the state-of-the-art approaches for real image SR in terms of PSNR
and SSIM.
