Abstract
Architectural illustration using line drawing with colorization is an important tool and art format. In this paper, in order to generate a natural-looking and high quality water colorlike colorization for architectural line drawing, we propose a novel Generative Adversarial Network (GAN) approach, namely ArchGANs. The proposed ArchGANs unifies a line-feature-aware stylized colorization network (ArchColGAN), which can learn, predict and generate the coloring based on a dataset, as well as a shading generation network (ArchShdGAN), which augments the illustration with controllable lighting effects for better depicting building in 3D. Specifically, ArchColGAN can preserve the essential line features and building part correlation property, it also tackles the uneven colorization problem caused by the sparse lines. Experimental results demonstrate our proposed method is effective and suitable for colorization prototyping.
