Intelligent Typography: Artistic Text Style Transfer for Complex Texture and Structure

Abstract

Text style transfer is an important task to render artistic texts from a reference image or style, and is widely desired in many visual creations. Previous works have brought some efficient methods for text style transfer, which facilitate users to design various artistic texts automatically. However, these works mainly focus on relatively simple text effects, and do not perform well on complex reference styles. In this paper, we propose a coarse-to-fine framework to generate exquisite texts with complex texture and structure in an unsupervised way, achieving real-time control of style scales (i.e., text stylistic degree or deformation degree). The key idea is to decouple the overall task into two steps, prototype generation and detail refinement, and explore delicate networks for each step to imitate the features at different levels. Based on this idea, in the first step, we present a novel pro-gen GAN to generate prototypes of artistic texts using the reference style, and develop a deformable module to empower the pro-gen GAN to continuously characterize the multi-scale shape features without network retraining. Furthermore, we propose a mix-attention training scheme for text style transfer, which can avoid artifacts and retain a clear text background. In the second step, we introduce two optimized networks for detail refinements. Experimental results show that the proposed method can synthesize exquisite stylized texts with complex reference styles, and surpass the state of the arts in texture reconstruction, contour imitation, and text image quality drastically.
