摘要
本文回顾了NTIRE 2022高效单图像超分辨率挑战赛，重点介绍所提出的解决方案与结果。该挑战赛的任务是基于低分辨率与对应高分辨率图像对，以 4 的放大因子对输入图像进行超分辨率重建。其目标是设计一种单图像超分辨率网络，在根据包括运行时间、参数量、FLOPs、激活值和内存消耗在内的多项指标衡量的效率得到提升的同时，至少在DIV2K验证集上保持29.00dB的PSNR。IMDN被设为效率测量的基线。该挑战赛包含3个赛道：主赛道（运行时间）、子赛道一（模型复杂度）和子赛道二（综合性能）。在主赛道中，评估了提交方案的实际运行时间表现。团队排名由验证集和测试集上平均运行时间绝对值直接决定。在子赛道一中，考虑了参数量和FLOPs。并将两项指标的各自排名相加以确定该赛道的最终排名。在子赛道二中，考虑了挑战赛描述中提到的全部五项指标，包括运行时间、参数量、FLOPs、激活值和内存消耗。与子赛道一类似，将五项指标的排名相加以确定最终排名。该挑战赛有303名注册参与者，43支团队提交了有效方案。它们标定了高效单图像超分辨率的最先进水平。
