摘要：当前的 HDR 显示技术接近完全适应的人类视觉系统的动态范围能力。因此，该技术有潜力在高动态范围 (HDR) 图像再现算法的感知评估中作为现实世界场景的替代品，该算法旨在将 HDR 场景映射到典型显示和打印技术中可用的有限动态范围。与直接与真实场景进行图像评估相比，很明显，使用 HDR 显示技术的优点是实验设计简单，同时保持了原始场景的 HDR。为了评估 HDR 显示技术的潜在应用，针对实验室构建的四个真实世界场景以及 HDR 显示器上的相应图像，对七个已发布版本的著名 HDR 色调映射算法的感知渲染精度进行了基准测试。结果表明，从 HDR 显示获得的视觉评估与从真实世界场景获得的视觉评估非常一致，验证了 HDR 显示技术作为评估工具的潜力。
Abstract— Current HDR display technology approaches the dynamic‐range capabilities of the fully adapted human visual system. As such, this technology has potential for performing as a surrogate for real‐world scenes in the perceptual evaluation of high‐dynamic‐range (HDR) image‐reproduction algorithms that aim to map HDR scenes to the limited dynamic ranges available in typical display and print technology. Compared with direct image assessment in comparison with real‐world scenes, it is clear that use of HDR display technology has the benefit of simplicity in experimental design while maintaining the HDR of the original scene. To evaluate this potential application of HDR display technology, seven published versions of well‐known HDR tone‐mapping algorithms were benchmarked for perceptual rendering accuracy against each of four real‐world scenes constructed in the laboratory and against corresponding images on an HDR display. The results illustrate that visual assessments obtained from the HDR display and those obtained from real‐world scenes are in good agreement, validating the potential for HDR display technology as an evaluation tool in this context.
