This paper reviews the Challenge on Image Demoireing that was part of the New
Trends in Image Restoration and Enhancement (NTIRE) workshop, held in
conjunction with CVPR 2020. Demoireing is a difficult task of removing moire
patterns from an image to reveal an underlying clean image. The challenge was
divided into two tracks. Track 1 targeted the single image demoireing problem,
which seeks to remove moire patterns from a single image. Track 2 focused on
the burst demoireing problem, where a set of degraded moire images of the same
scene were provided as input, with the goal of producing a single demoired
image as output. The methods were ranked in terms of their fidelity, measured
using the peak signal-to-noise ratio (PSNR) between the ground truth clean
images and the restored images produced by the participants' methods. The
tracks had 142 and 99 registered participants, respectively, with a total of 14
and 6 submissions in the final testing stage. The entries span the current
state-of-the-art in image and burst image demoireing problems.

本文讨论了 NTIRE 和 CVPR2020 共同举办的图像去莫尔雾化挑战，分为单幅和爆发式两类不同的图像去莫尔雾化问题，评估了 14 个和 6 个不同方法的还原图像的质量，探讨了在图像和爆发式去莫尔雾化问题中现有领先的技术。
