Abstract
When creating 2D illustrations, painting is quite important because different painting of the same line drawings can give completely different impressions. To assist in painting of line drawings, we propose two methods that can transfer the painting information of a reference illustration to an un-painted line drawing. Both input images are first segmented into closed regions, and the rough shape of each region is estimated as a normal map. The user can select corresponding regions between the two input images, and transfer painting information based on the normal maps, just like using a color palette.
