书法是一种文字或字母的安排，创造了一个视觉形象，一个紧凑的书法适合一个字到一个2D形状。我们介绍了一种全自动的方法，用于生成清晰紧凑的书法，它提供了一个平衡之间的传达输入形状，易读性和美学。我们的方法有三个关键要素：一个路径生成步骤，计算一个全球布局路径适合嵌入输入单词;一个对齐步骤，放置字母，以实现字母和形状突起之间的功能对齐，同时保持单词的易读性;和一个最终的变形步骤，变形的字母，以适应形状，同时平衡适合对字母易读性。由于字母易读性对紧凑书法的质量至关重要，我们对不同字母变形对易读性的影响进行了大规模的众包研究，并使用结果来训练指导字母变形的字母易读性度量。我们显示自动生成的一组广泛的字图像组合的书法。通过用户研究，对书法的易读性和整体质量进行了评估和比较，与人类创作者（包括专业艺术家）和现有作品的书法进行了比较。
A calligram is an arrangement of words or letters that creates a visual image, and a compact calligram fits one word into a 2D shape. We introduce a fully automatic method for the generation of legible compact calligrams which provides a balance between conveying the input shape, legibility, and aesthetics. Our method has three key elements: a path generation step which computes a global layout path suitable for embedding the input word; an alignment step to place the letters so as to achieve feature alignment between letter and shape protrusions while maintaining word legibility; and a final deformation step which deforms the letters to fit the shape while balancing fit against letter legibility. As letter legibility is critical to the quality of compact calligrams, we conduct a large-scale crowd-sourced study on the impact of different letter deformations on legibility and use the results to train a letter legibility measure which guides the letter deformation. We show automatically generated calligrams on an extensive set of word-image combinations. The legibility and overall quality of the calligrams are evaluated and compared, via user studies, to those produced by human creators, including a professional artist, and existing works.
