Improving arc detection in graphics recognition
Philippe Dosch, Gérald Masini, Karl Tombre · 2002
In the context of graphics recognition, arc detection consist in the extraction of circles and arcs from the image of a graphics document or from the segments yielded by its vectorization. Several methods have been proposed for this purpose, and we briefly survey them. Then, we describe an improved algorithm inspired by two existing methods, and including a fitting step for better precision.
