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 ...
Singularity-free frame fields for line drawing vectorization
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. ...
