高王是在日本历史文献研究领域中占有重要地位的史料之一。在高王的研究中，历史学家必须走访日本各地进行整理，这是高王研究的一大难点。此外，日本约有40万个高王。本文提出了一种使用流畅功能化图像的 Kaoh 数据库系统，目的是编译 Kaoh 图像并通过互联网在研究人员之间共享。流畅函数化图像是图像中各区域的轮廓用流畅函数来近似的图像类型。实验结果表明，即使经过仿射变换，图像仍保持Kaoh图像的形状特征，并且数据量比原始位图图像小得多。
Kaoh is one of historical materials which plays an important role in the field of historical document research in Japan. In the research of Kaoh,the historian must visit various places in Japan to compile them, which is a major difficulty in Kaoh research. In addition, there exist approximately 400,000 Kaohs in Japan. This paper proposes a Kaoh database system using fluency functionalized images, for the purpose of compiling the Kaoh images and sharing them among the researchers via the Internet. Fluency functionalized image is the type of image that the contours of each region in the image are approximated with fluency functions. From the experimental results, it was shown that the images kept the shape characteristics of Kaoh images even after affine-transforms, and that the data size were much smaller compared with the original bitmap images.
