论文摘要

本文回顾了NTIRE 2020对感知极端超分辨率的挑战，重点是拟议的解决方案和结果。挑战任务是基于一组先前的低分辨率图像和相应的高分辨率图像的先前示例，具有放大因子16的超级溶解输入图像。目的是获得能够以最佳感知质量和类似地面真理产生高分辨率结果的网络设计。该赛道有280名注册参与者，19个团队提交了最终结果。他们在单图超分辨率中评估了最新的。

This paper reviews the NTIRE 2020 challenge on perceptual extreme super-resolution with focus on proposed solutions and results. The challenge task was to super-resolve an input image with a magnification factor 16 based on a set of prior examples of low and corresponding high resolution images. The goal is to obtain a network design capable to produce high resolution results with the best perceptual quality and similar to the ground truth. The track had 280 registered participants, and 19 teams submitted the final results. They gauge the state-of-the-art in single image super-resolution.
