Quantitative Analysis and Visualization of Color Information in Art

1.颜色信息定量分析的数学基础研究开发了一种OSA-UCS到CIEXYZ的转换算法，对PCS和孟塞尔系统之间的关系进行了数学研究，并引入了NCS颜色空间中颜色值之间的数学距离。数码相机准确记录博物馆材料中色彩信息的研究用数码相机准确记录“浮世绘”和“和服”的色彩信息的实验表明了数码相机的能力，并揭示了在记录色彩信息方面的一些问题。艺术作品中色彩信息的定量分析提出了一种用于图像分析的色彩空间变异结构的提取和可视化方法，提出了绘画艺术中色彩变异的粗糙度的数学分析方法，并对日本古代宫廷服饰中的色彩组合进行了计算分析。面向科研和教学的色彩信息处理与可视化工具“Colored”的开发开发了一个色彩信息处理工具，它是Windows-Excel的一个加载宏。该工具用于颜色信息的可视化和各种颜色规范系统之间的颜色值转换。与法国色彩联合会主席米歇尔·阿尔伯特·瓦内尔教授的合作研究与米歇尔·阿尔伯特·瓦内尔教授就颜色组合的颜色分类空间的开发和绘画艺术中的色彩构成分析进行了研究。

1. Basic Mathematical Studies for Quantitative Analysis of Color InformationDeveloped an OSA-UCS to CIEXYZ conversion algorithm, made mathematical studies on relation between PCCS and Munsell systems, and introduced mathematical distance between color values in NCS color space.2. Studies on Accurate Recording of Color Information in Museum Materials by Digital Still CamerasExperiments on accurate recording of color information of "ukiyo-e" and "kimono" by digital still cameras showed the capability of digital still cameras and revealed some issues in recording color information.3. Quantitative Analysis of Color Information in Art WorksProposed a method for extraction and visualization of structure of spatial variation of color for image analysis, proposed a method for mathematical analysis of coarseness of color variation in painting arts, and made a computational analysis of color combination in "kasane-irome", Japanese ancient court costume.4. Development of "Colored", a Processing and Visualization Tool of Color Information for Research and EducationDeveloped a color information processing tool, which is an add-in macro of Windows-Excel. The tool is designed for visualization of color information and transformation of color values among various color specification systems.5. Co-research with Prof. Michel Albert-Vanel ( President of French Color Federation )Proceeded the studies with Prof.Michel Albert-Vanel on development of a color classification space of color combinations and on analysis of color composition in painting arts.
