摘　　要：艺术字体渲染是媒体排版的重要技术之一.如何提供一种高效的艺术字体渲染方法来实现生成艺术字体的特效多样化与清晰化是亟待解决的问题.本文借助条件生成式对抗网络(Conditional Generative Adversarial Networks,CGAN),提出一个包括风格化处理和清晰化处理的二阶段式艺术字体渲染方法,对字体实现高效的特定效果渲染.首先,风格化处理是通过构建风格化网络模型对多样化的字体进行各种不同的2D或3D特效渲染;然后,构建清晰化网络模型对生成的艺术字体图进行清晰化处理,这克服了单一GAN网络生成图模糊的缺陷.实验结果表明,二阶段式艺术字体渲染方法所生成的特效字体的纹理细节较为丰富,不受限于文字骨架,而且字体清晰度也得到较大提升;同时,该方法对字体的特效渲染批量化处理效率也明显提高,具有较强实用价值.Art font rendering is one of the important techniques of media typesetting.How to provide an efficient art font rendering method to realize the diversity and clearness of the special effects of generative art fonts is an urgent problem for technicians in this field.With the help of Conditional Generative Adversarial Networks (CGAN),a two-stage art font rendering method that includes style transfer processing and enhancement processing is proposed to achieve high quality rendering of art fonts.First,by style transfer processing,a stylized network model is built to render various 2D or 3D special effects on a variety of input fonts.Then,by enhancement processing,a sharpening network model is built to sharpen the generated art font images,which overcomes the defect of fuzzy image generation in a single GAN network.The experimental results show that,comparing with existing methods,this scheme has a better performance for generating more diverse and more clear special art fonts, whose texture details are relatively rich,and are not limited to the text skeleton.At the same time,this scheme can also improve the efficiency of art font rendering in the batch processing and has a higher practical value.
