Fig. 1. Free-hand sketches use clusters of strokes (a, each cluster colorized in different color) to depict intended aggregate curves. Existing methods that aim to fit aggregate curves to vector stroke clusters (b,c) frequently produce outputs inconsistent with artist intent and viewer expectations (e.g. nose, mouth, left eyebrow (b,c); insets show the point orderings they generate and use to compute fits, visualized using a red to blue color scheme). StrokeStrip jointly arc length…

TLDR
This approach enables greater conceptual freedom during visual ideation activities by allowing designers to develop their sketches using multiple, casually drawn strokes without requiring them to indicate the separation between different stroke groups.
StrokeAggregator: consolidating raw sketches into artist-intended curve drawings
TLDR
StrokeAggregator is proposed, a novel stroke consolidation method that significantly improves on the state of the art, and produces aggregate curve drawings validated to be consistent with viewer expectations.
Just DrawIt: a 3D sketching system
TLDR
A sketch-based system for creating 3D curves suitable for surfacing, based on unintrusive context-aware, in-screen pie menus designed for rapid pen-based input, which provides novel rendering styles and aides for interpreting and working with 3D sketches.
Integer‐Grid Sketch Simplification and Vectorization
TLDR
This work proposes to extract vector curve networks by parametrizing the image with local drawing‐aligned integer grids, and demonstrates that this method successfully vectorizes both clean and rough line drawings, whereas previous methods focused on only one of those drawing types.
Closure-aware sketch simplification
TLDR
This paper points out that, due to the gestalt phenomenon of closure, the grouping of strokes is actually highly influenced by the interpretation of regions, and solves the chicken-or-the-egg dilemma by an iterative cyclic refinement approach to simplify sketch drawings.
Sketching Clothoid Splines Using Shortest Paths
TLDR
This work describes a novel algorithm for approximating a sketched stroke with a fair clothoid spline, and demonstrates that the curves produced by the method have good curvature profiles, while staying close to the user sketch.
A complete hand-drawn sketch vectorization framework
TLDR
A complete framework that automatically transforms noisy and complex hand-drawn sketches with different stroke types in a precise, reliable and highly-simplified vectorized model is proposed, suitable for integration in any computer graphics toolset.
An Accurate System for Fashion Hand-Drawn Sketches Vectorization
TLDR
This paper proposes a system for automatic vectorization of fashion hand-drawn sketches based on Pearson's Correlation Coefficient with multiple Gaussian kernels in order to enhance and extract curvilinear structures in a sketch.
Topology-driven vectorization of clean line drawings
TLDR
This work proposes a vectorization algorithm specialized for clean line drawings that analyzes the drawing's topology in order to overcome junction ambiguities and demonstrates results on professional examples and evaluates the vectorization quality with quantitative comparison to hand-traced centerlines as well as the results of leading commercial algorithms.
