  • Differential operators on sketches via alpha contours 

    Myronova, Mariia; Neveu, William; Bessmeltsev, Mikhail (Association for Computing Machinery, 2023-08)
    A vector sketch is a popular and natural geometry representation depicting a 2D shape. When viewed from afar, the disconnected vector strokes of a sketch and the empty space around them visually merge into positive space and negative space, respectively. ...

  • Singularity-free frame fields for line drawing vectorization 

    Guțan, Olga; Hegde, Shreya; Jimenez Berumen, Erick; Bessmeltsev, Mikhail; Chien, Edward (Wiley, 2023-07-19)
    State-of-the-art methods for line drawing vectorization rely on generated frame fields for robust direction disambiguation, with each of the two axes aligning to different intersecting curve tangents around junctions. However, a common source of ...
