Novel "Shin-hanga" Filter using Segmentation and Gradation
Details
This filter converts an image into multi-colored block print style, "Shin-hanga," which was once popular in Japan around one hundred years ago. We expect that this filter sheds light again on this obsolete but fascinating art style. This filter follows these three steps; first, the filter extracts contour lines based on hue of an image, then segments areas based on those contour lines, and finally determines the gradation of color and the direction of it, which is vertical or horizontal, based on the amount and the direction of variation of hue in each area. Also, we conducted an experiment to assess the domain of applicability of this filter. And then, we clarified its problems and possible solutions.
