Quantitative Analysis of Aesthetic Information of Color in Modern Japanese Kimono and its Application to Color Designing

本研究取得的主要成果有：1.为了准确测量和服的颜色信息，我们对日本国立历史博物馆保存的野村收藏的部分kosode进行了彩色图像记录。在项目过程中，对和服颜色信息测量中的一些关键问题进行了澄清。这些问题包括：a)光照条件，b)测量的稳定性和c)丝织物特有的反射的处理。2.研究了用数码相机记录和服的颜色信息。2004年12月，我们在京都举行的IPSJ/SIG CH(日本信息处理学会/SIG计算机和人文科学)研讨会上发表的关于使用数码相机的数字档案的研究获得了山下纪念奖。介绍了利用数码相机记录博物馆历史资料彩色图像的进一步研究。3.真丝织物的颜色受光照和视觉条件的影响很大，也受纤维的方向影响。对典型缎纹织物的光谱反射系数进行了三维测量，明确了其反射的定性特征。此外，还提出了具有复杂表面结构的斜纹织物的宏观模型。该模型与织物的实际反射率具有较好的一致性。4.对用于平安贵族宫廷服饰的日本传统配色系统Kasane-irome进行了计算分析，开发了Kasane-irome可视化软件系统。5.开发了多种颜色信息的计算分析方法，并将其应用于和服的颜色信息分析。6.在CSAJ(日本色彩科学协会)期刊上发表了一篇题为《江户时代和服色彩信息分析研究》的论文。另外两篇与这项研究有关的报告也被投稿给了该杂志。

The major achievements of our research are :1.Aiming to measure accurate color information of kimono, we conducted a project to record color images of some kosode of the Nomura Collection preserved by the National Museum of Japanese History. During the project, some essential issues relating to measurement of color information of kimono were clarified. Those issues include : a)lighting condition, b)stability of measurement and c)treatment of reflections peculiar to silk fabrics.2.Studies concerning recording of color information of kimono using digital cameras were performed. Our studies on digital archive using digital cameras presented at the IPSJ/SIG CH(Information Processing Society of Japan/SIG Computers and the Humanities) symposium in Kyoto on Dec.2004 received the Yamashita Memorial Prize. Further studies on recording of color images of historical materials in museums using digital cameras were introduced.3.Color of silk fabrics are strongly affected by the lighting and visual conditions and also by the direction of the fiber. We performed three dimensional measurement of the spectral reflectance factor of typical satin fabrics and clarified their qualitative characteristics of reflectance. Furthermore a macro model for twill fabrics having complex surface structures was proposed. This model shows good agreement to the actual reflectance of the fabrics.4.Computational analyses of kasane-irome, a traditional Japanese color combination system applied to the court costumes of Heian aristocracy, were performed, and a software system to visualize kasane-irome was developed.5.Various methods for computational analysis of color information were developed, which were applied to the analyses of color information of kimono.6.A paper titled "A Study on the Analysis of Color Information of Kimono in the Edo-era" was adopted in the CSAJ(Color Science Association of Japan) journal. Two more reports relating to the study were also contributed to the journal.
