Abstract
Binary shapes, or silhouettes, are building elements of logos, graphic
symbols and fonts, which require various forms of geometric editing
without compromising the resolution. In this paper, we present an
effective silhouette vectorization algorithm that extracts the outline
of a 2D shape from a raster binary image and converts it to a
combination of cubic Bézier polygons and perfect circles. Compared to
state-of-the-art image vectorization software, this algorithm has
demonstrated a superior reduction in the number of control points while
maintaining high accuracy.
