Réjean Plamondon, Guy Lorette · 2005
This paper presents a survey of the major achievements in automatic signature verification based on dynamic or on-line techniques. After a review of preprocessing techniques a special attention is given to feature extraction methods and comparison processes with respect to the two basic representa tions of a signature: functions and parameters. Comparative results of performance are then presented and discussed.
