Zusammenfassung
Automatic conversion of line drawings from paper to elec-
tronic form requires the recognition of geometric primitives like lines,
arcs, circles etc. in scanned documents. Many algorithms have been pro-
posed over the years to extract lines and arcs from document images.
To compare different state-of-the-art systems, an arc segmentation con-
test was held in the seventh IAPR International Workshop on Graph-
ics Recognition - GREC 2007. Four methods participated in the con-
test, three of which were commercial systems and one was a research
algorithm. This paper presents the results of the contest by giving an
overview of the dataset used in the contest, evaluation methodology,
participating methods and the segmentation accuracy achieved by the
participating methods.
