Abstract : We present a fast and efficient algorithm for the semi-supervised colorization of line-arts (e.g. handmade cartoons), based on two successive steps: 1. The analysis of the local stroke geometry, and their possible closing by splines/segments, and 2. The colorization by the filling of connex regions with random colors, or by the extrapolation of color markers set by the user. Our method renders colorization of similar quality compared to state of the arts algorithms, while having a lower algorithmic complexity, leading to more possible user interactivity.
