Abstract

We propose a photographic method to show scalar values of high dynamic range (HDR) by color mapping for 2D visualization. We combine (1) tone-mapping operators that transform the data to the display range of the monitor while preserving perceptually important features, based on a systematic evaluation, and (2) simulated glares that highlight high-value regions. Simulated glares are effective for highlighting small areas (of a few pixels) that may not be visible with conventional visualizations; through a controlled perception study, we confirm that glare is preattentive. The usefulness of our overall photographic HDR visualization is validated through the feedback of expert users.

摘要

我们提出一种摄影方法，通过颜色映射来展示高动态范围（HDR）的标量值，以进行二维可视化。我们结合了：（1）基于系统评估的色调映射运算符，该运算符在保留感知上重要特征的同时将数据转换到显示器的显示范围；以及（2）突出显示高值区域的模拟眩光。模拟眩光对于突出显示传统可视化可能无法看到的小区域（几个像素）很有效；通过一项受控的感知研究，我们证实眩光具有预注意性。我们整体的摄影HDR可视化的实用性通过专家用户的反馈得到了验证。
