Recognition of Arrows in Line Drawings based on the Aggregation of Geometric Criteria using the Choquet Integral

1 QGAR - Querying Graphics through Analysis and Recognition

A new way to detect arrows in line drawings is proposed in this paper. Our approach is based on the definition of the structure of such a symbol. Signatures of angular areas are computed and axiomatic properties and geometric characteristics are checked using the Choquet integral. Finally an experimental application on line-drawing documents shows the interest of our approach.
