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. ... -
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 ... -
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 ... -
Sketch2Pose : estimating a 3D character pose from a bitmap sketch
Brodt, Kirill; Bessmeltsev, Mikhail (Association for computing machinery, 2022-07-22)Artists frequently capture character poses via raster sketches, then use these drawings as a reference while posing a 3D character in a specialized 3D software --- a time-consuming process, requiring specialized 3D training and mental effort. We tackle ...
