  • Keypoint-driven line drawing vectorization via polyvector flow 

    Puhachov, Ivan; Neveu, William; Chien, Edward; Bessmeltsev, Mikhail (Association for Computing Machinery, 2021-12)
    Line drawing vectorization is a daily task in graphic design, computer animation, and engineering, necessary to convert raster images to a set of curves for editing and geometry processing. Despite recent progress in the area, automatic vectorization ...

  • 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 ...
