  • 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 ...

  • Reconstruction of machine-made shapes from bitmap sketches 

    Puhachov, Ivan; Martens, Cedric; Kry, Paul G.; Bessmeltsev, Mikhail (Association for computing machinery, 2023-12)
    We propose a method of reconstructing 3D machine-made shapes from bitmap sketches by separating an input image into individual patches and jointly optimizing their geometry. We rely on two main observations: (1) human observers interpret sketches ...
