Abstract

A technology known as pix2pix has made it possible to automatically color line drawings. However, its accuracy is based on the quality of the characteristic lines, which emphasize the characteristics of the subject drawn in the line drawing. In this study, we propose a method for automatically generating characteristic lines in line drawings. The proposed method uses pix2pix to learn the relationship between the contour line drawing and line drawing with characteristic lines. The obtained model can automatically generate a line drawing with the characteristic lines from the contour line drawing. In addition, the quality of the characteristic lines could be adjusted by adding various degrees of blurring to the training images. In our experiments, we qualitatively evaluated the line drawings of shoes generated using the proposed method. We also applied an existing automatic coloring method using pix2pix to line drawings generated using the proposed method and confirmed that the desired colored line drawing could be obtained.
