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

研究了场景与介质在不同光照条件下自动实现“对应色彩再现”的两种技术。首先，我们成功地开发了一种新的基于图像不完全分割和二色反射模型的鲁棒照明色度估计方法。这种方法特别适用于人工制品的图像。其次，我们在两台白点不相同的显示器上对彩色图像进行了人类色觉的不完全色度适应实验。对8对白色色度对的实验显示出有趣的结果：得到的不完全适应系数既不恒定也不对称，人类的色觉适应于靠近两个白点中较低的一个的色温。

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.
