      A person's handwriting appears differently within a typical range of variations, and the shapes of handwriting characters also show complex interaction with their nearby neighbors. This makes automatic synthesis of handwriting ...
    • FlexyFont: Learning Transferring Rules for Flexible Typeface Synthesis 

      Phan, Huy Quoc; Fu, Hongbo; Chan, Antoni B. (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Maintaining consistent styles across glyphs is an arduous task in typeface design. In this work we introduce Flexy- Font, a flexible tool for synthesizing a complete typeface that has a consistent style with a given small ...
    • Tone- and Feature-Aware Circular Scribble Art 

      Chiu, Chun-Chia; Lo, Yi-Hsiang; Lee, Ruen-Rone; Chu, Hung-Kuo (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Circular scribble art is a kind of line drawing where the seemingly random, noisy and shapeless circular scribbles at microscopic scale constitute astonishing grayscale images at macroscopic scale. Such a delicate skill ...
