FlexiFont: a flexible system to generate personal font libraries

This paper proposes FlexiFont, a system designed to generate personal font libraries from the camera-captured character images. Compared with existing methods, our system is able to process most kinds of languages and the generated font libraries can be extended by adding new characters based on the user's requirement. Moreover, digital cameras instead of scanners are chosen as the input devices, so that it is more convenient for common people to use the system. First of all, the users should choose a default template or define their own templates, then write the characters on the printed templates according to the certain instructions. After the users upload the photos of the templates with written characters, the system will automatically correct the perspective and split the whole photo into a set of individual character images. As the final step, FlexiFont will denoise, vectorize, and normalize each character image before storing it into a TrueType file. Experimental results demonstrate the robustness and efficiency of our system.
