To this aim, we propose a parameterfree method to detect the hierarchical set of stroke contours. Line-drawings have long been considered as a very important study in artist preliminary works [Kan79, Kle04]. In this paper, we first propose in Section 2 a parameterfree approach to detect closed contours in line-drawings. description of line-drawing is based on the curvature distribution (Section 3.2) and on the detection of several visual circular tool, for each stroke cluster Φ associated with a coalescence set made of n level lines Li, the tool radius RΦ is Figure 3: Left, maximal meaningful level lines from a drawing, and its superposed curvature zero-crossings. To detect stroke endpoints, the set of negative curvature In this paper we introduced a method for the pictorial content analysis of line drawings using the geometrical information of stroke contours.	./cache/work_onmsvvzkszb6fahqgfffu3qpty.pdf	./txt/work_onmsvvzkszb6fahqgfffu3qpty.txt
