A Study on the Automatic Realization of Corresponding Color Reproduction between a Scene and Various media.

研究了两种在不同光照条件下自动实现场景与媒体“对应色彩再现”的技术，首先，提出了一种基于不完全图像分割和双色反射模型的稳健光照色度估计方法。其次，我们对白点不同的两种显示器上的彩色图像进行了人类颜色视觉的不完全色适应实验。对8个白色色度对的实验表明，得到的不完全适应系数既不是恒定的，也不是对称的，人类的色觉适应于两个白点中较低的一个附近的色温。

Two technologies for the automatic realization of "corresponding color reproduction" between a scene and media under various illumination conditions were studied.First, we succeeded in developing a new robust illumination chromaticity estimation method, which is based on the incomplete image segmentation and the di-chromatic reflection model. This method works especially well for the images of artifacts.Second, we conducted experiments on incomplete chromatic adaptation of human color vision between color images on two displays, whose white points are not the same. The experiments for eight white chromaticity pairs showed interesting results that the obtained incomplete adaptation coefficients are neither constant nor symmetric, and the human color vision adapts to the color temperature that is near the lower one of the two white points.
