4 - Des gaussiennes pour la modélisation des signatures et la segmentation de tracés manuscrits

This paper presents the use of a handwriting generation mode! for signature reconstruction and word segmentation . This mode! is based on two velocity generators : a curvilinear velocity generator and an angular velocity generator . In the curvilinear and the angular domains, the mode! estimates velocity profiles with a series of gaussian curves . In the first part of this paper, the theoretic mode! and the underlying concepts are described. Then the validity of the mode! is tested on various kind of signatures (european, chinese, north-american) . At the end of this paper the mode! is used for cursive word segmentation and the results are discussed.
