An Online Writer Identification System based on Beta-Elliptic Model and Fuzzy Elementary Perceptual Codes.

Actually, the ability to identify the documents authors provides more chances for using these documents for various purposes. In this paper, we present a new effective biometric writer identification system from online handwriting. The system consists of the preprocessing and the segmentation of online handwriting into a sequence of Beta strokes in a first step. Then, from each Beta stroke, we extract a set of static and dynamic features using four features extraction techniques based on the Beta Elliptic model and the Fuzzy Elementary Perceptual Codes. Next, all the segments which are composed of N consecutive Beta strokes are categorized into groups and subgroups according to their position and their geometric characteristics. Finally, Deep Neural Network are used for classification. Experimental results reveal that the proposed system achieves interesting results as compared to those of the existing writer identification systems on Latin and Arabic scripts.
