Singularity-free frame fields for line drawing vectorization
(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. ...
Keypoint-driven line drawing vectorization via polyvector flow
(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 ...
