Study of Digital Archives and Retrieval System for Ukiyo-e

我们提出了一个帮助用户识别和检索浮世绘图像和信息的系统。Rakkan是一个日语单词，意思是艺术家在完成的艺术作品上的签名。使用所提出的系统，用户可以通过图形用户界面从数字化浮世绘图像中选择感兴趣的rakkan区域。在L*a*b*颜色空间中使用k-均值聚类或基于规则的二值化从所选区域自动提取rakkan字符，并将其归一化以作为查询图像进行检索处理。采用方向梯度直方图和互相关法进行检索。该系统可用于浮世绘作者身份识别和浮世绘绘画检索，用于浮世绘研究和存档。

We proposed a system that helps the users to identify and retrieve rakkan images and information of ukiyo-e paintings. Rakkan is a Japanese word for the signature of the artist for a completed art work. Using the proposed system, the user can select the rakkan area of interest from a digitalized ukiyo-e image via a graphical user interface. The rakkan characters are automatically extracted from the selected area using k-means clustering or a rule-based binarization in L*a*b* color space, and normalized for retrieval process as a query image. Histogram of oriented gradients and cross-correlation are used for retrieval. The proposed system can be adapted to ukiyo-e authorship identification and ukiyo-e painting retrieval for ukiyo-e study and archiving.
