本文提出了一种改进的从给定的木刻版画图像中估计木刻和颜料颜色的方法。Terai等人。已经提出了一种颜色分解方法[Terai2004]。前一种方法仅用于从观测图像中估计对应于水彩的每个印刷区域。它通过从给定图像的CIE L∗u∗v∗颜色分布确定回归四边形来实现这一点。本文提出的方法是基于被估计的四边形理想地形成一个梯形，并且使用比L∗u∗v∗更线性的CIE XY Z颜色空间来进行水彩画的混色。通过一个实际的Ukiyo-e印刷品的实验，证明了该方法的有效性。
This paper proposes an improved method to estimate woodblocks and pigment colors from a given woodblock print image. Terai et al. have already proposed a color decomposition method [Terai2004]. The former method is only used to estimate each of the printed areas which corresponds to a watercolor from the observed image. It does this by determining a regression tetragon from the CIE L∗u∗v∗ color distribution of the given image. The proposed method in this paper is based on the fact that the estimated tetragon ideally forms a trapezoid, and also that it uses CIE XY Z color space which is more linear than CIE L∗u∗v∗ for color mixing of watercolors. The usefulness of the proposed method is demonstrated by an experiment using an actual Ukiyo-e print.
