Interactive Manga Colorization with Fast Flat Coloring

This paper proposes an interactive semi-automatic system for manga colorization. In our system, users can colorize monochrome manga images interactively by scribbling the desired colors. The proposed method creates a high quality colorized image by inputting the original monochrome image after grayscale adjustment and the flat colored image generated from the scribbles to a colorization network. Experiments show that the colorized results yielded by the proposed method are much better than existing methods.
