在现实世界中，我们可以找到很大的亮度范围：场景中最亮和最暗的部分的比例可以达到10000比1的量级。由于我们大多数的电子显示器都有大约100到1的有限范围，在过去的20年里，我们已经做了很多工作来开发不同的算法，将图像的实际动态范围压缩到显示设备中可用的范围。这些算法被称为色调映射，试图尽可能多地保留图像特征。越来越多的研究也在试图评估“最好的”音调映射器。方法包括对色调映射图像[2]的明智比较，与真实场景[3]的比较或使用高动态范围（HDR）监视器[4]上显示的图像。这些方法都不完全令人满意，并且由于参与者对指示和偏见的解释，都存在潜在的混淆因素。有证据表明，观察者在观看图像时所产生的注视的空间和时间路径（即扫描路径）在某种程度上是重复的，当同一图像再次呈现给观察者时（例如[5]）。在这篇论文中，我们是第一个研究使用眼动记录，特别是扫描路径作为歧视工具的可能性的人。我们建议，如果色调映射图像产生的扫描路径与观看原始图像时获得的扫描路径不同，这可能表明色调映射器质量较差，因为它引起的眼球运动与观看原始图像时观察到的眼球运动不同。
In the real world we can find large intensity ranges: the ratio from the brightest to the darkest part of the scene can be of the order of 10000 to 1. Since most of our electronic displays have a limited range of around 100 to 1, the last 20 years has seen much work done to develop different algorithms that compress the actual dynamic range of an image to that available in the display device. These algorithms, known as tone mappers, attempt to preserve as much of the images characteristics as possible [1]. An increasing amount of research has also been done to try to evaluate the 'best' tone mapper. Approaches have included pair wise comparisons of tone mapped images [2], comparison with real scenes [3] or using images displayed on a High Dynamic Range (HDR) monitor [4]. None of these approaches are entirely satisfactory and all suffer from potential confounding factors due to participant's interpretation of instructions and biases. There is evidence that the spatial and chronological path of fixations made by observers' when viewing an image (i.e. the scanpath) is repeated to some extent when the same image is again presented to the observer (e.g. [5]). In this paper we are the first to investigate the potential of using eye movement recordings, particularly scanpaths, as a discriminatory tool. We propose that if a tone-mapped image gives rise to scanpaths that are different from those obtained when viewing the original image this might be an indication of a poor quality tone mapper since it is eliciting eye movements that are different from those observed when viewing the original image.
