ABSTRACT
The vectorization process transforms an image in the algebraic representation of if its contours. In the case of hand-drawn cartoons, the pen stroke made by the artist defines such a contour. That's why drawing can be interpreted as a series of junctions between nodes, or, in other words, as a topological graph.
Many softwares tackle this subject (Adobe Live Trace, Win-Topo...). We will focus here on a program developed in 2013 by a team of researchers from the ETH Zurich and Disney Studios [Noris et al. 2013]. Their method was very efficient for solving ambiguous cases in the drawing, however their implementation was very slow: the vectorization of a 2048x2048 cartoon could need more than 3 minutes of computation. We have improved their method achieving interactive speeds.

Interactive shade control for cartoon animation
SIGGRAPH '07: ACM SIGGRAPH 2007 postersShade in traditional cel animation is an essential element and plays a symbolic role in the artistic portrayal of character and scene. The shade on a character's face can be used to show emotion such as anger, sadness and hatred. Despite its usability, ...
