我们提出了一个简单的和具有成本效益的方式来扩展对比度，感知色调分辨率，和反射媒体，如纸张打印，硬拷贝照片，或电子纸显示器的色彩空间。一个校准的投影仪相机系统应用于自动配准，辐射扫描和叠加。在这种介质的表面上的投影光的第二调制导致高动态范围可视化。这在放射学、天文学、光学显微镜、历史艺术的保护和修复、现代艺术和娱乐设施等各个领域都有应用潜力。
We present a simple and cost-efficient way of extending contrast, perceived tonal resolution, and color space of reflective media, such as paper prints, hardcopy photographs, or electronic paper displays. A calibrated projector-camera system is applied for automatic registration, radiometric scanning and superimposition. A second modulation of the projected light on the surface of such media results in a high dynamic range visualization. This holds application potential for a variety of domains, such as radiology, astronomy, optical microscopy, conservation and restoration of historic art, modern art and entertainment installations.
