A benchmark for rough sketch cleanup

Chuan Yan, David Vanderhaeghe, Yotam Gingold
2020 ACM Transactions on Graphics  
ACKNOWLEDGMENTS We are grateful to all the artists who generously contributed their rough sketches to our dataset.  ...  We acknowledge the artists whose hard work created the ground truth data: Branislav Mirkovic, Santiago Rial, Diego Barrionuevo, Ge Jin, Jonathan Velasco, Liliya Larsen, and Maria Fiddler.  ...  ("in which a smaller set of lines is created to represent the geometry of the original lines" [Barla et al. 2005 ]), and cleanup or consolidation (clustering raw strokes into aggregate curves).  ...

Improved normal estimation from cross-section drawings

Silver Luciano Burla
2020
Accompanying our work is an updated sketch interface to make the drawing process more enjoyable for artists and designers.  ...  Cross-section curves enforce a set of geometric constraints that aid viewers in lifting and interpreting concept sketches into 3D space, and so readily supplement regularity cues and perceptual constraints  ...  Preliminary 2D analysis of raw input sketches is a crucial step in their pipeline that classifies strokes into axis-aligned scaffolding lines, other straight lines, and general curves, and consolidates  ...

StrokeStrip : joint parameterization and fitting of stroke clusters

Dave Pagurek Van Mossel
2021
When creating freeform drawings, artists routinely employ clusters of overdrawn strokes to convey intended, aggregate curves.  ...  The ability to algorithmically fit these intended curves to their corresponding clusters is central to many applications that use artist drawings as inputs.  ...  To process raw freehand vector sketches, these applications rely on sketch consolidation methods which cluster strokes that jointly depict individual intended curves, and then fit aggregate curves to each  ...

Ribbon drawing in VR : brushes and applications

We solve these problems by first developing SurfaceBrush, a surfacing method that converts such VR drawings into user-intended manifold free-form 3D surfaces.  ...  cover the surface of the intended shapes.  ...  Sheffer, StrokeAggregator: Consolidating Raw Sketches into Artist-Intended Curve Drawings, ACM Transactions on Graphics, (Proc SIGGRAPH 2018).
