Differential operators on sketches via alpha contours
(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 ...
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. ...
Reconstruction of machine-made shapes from bitmap sketches
(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 ...
Sketch2Pose : estimating a 3D character pose from a bitmap sketch
(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 ...
