Abstract

A new way to detect arrows in line drawings is proposedin this paper. Our approach is based on the definition of thestructure of such a symbol. Signatures of angular areas arecomputed and axiomatic properties and geometric characteristicsare checked using the Choquet integral. Finally anexperimental application on line-drawing documents showsthe interest of our approach.
