Abstract:
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. The former method is only used to estimate each of the printed areas which correspond to watercolor from the observed image. It does this by determining a regression tetragon from the CIE L 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 for color mixing of watercolors. The usefulness of the proposed method is demonstrated by an experiment using an actual Ukiyo-e print.
