摘要
本文回顾了作为 New Trends in Image Restoration and Enhancement（NTIRE）研讨会一部分、与 CVPR 2022 联合举办的限制性高动态范围（HDR）成像挑战赛。本手稿聚焦于竞赛设置、数据集、所提出的方法及其结果。该挑战赛旨在从多张各自的低动态范围（LDR）观测中估计 HDR 图像，这些观测可能存在欠曝光或过曝光区域以及不同来源的噪声。挑战赛由两条强调保真度与复杂度约束的赛道组成：在赛道 1 中，要求参与者在施加低复杂度约束（即解不能超过给定操作数）的同时优化客观保真度分数。在赛道 2 中，要求参与者在施加保真度分数约束（即解需获得高于规定基线的保真度分数）的同时最小化其解的复杂度。两条赛道使用相同的数据与指标：保真度通过相对于真实 HDR 图像的 PSNR 来衡量（直接计算及经典型色调映射操作后计算），而复杂度指标包括乘加（MAC）操作数和运行时间（以秒计）。
