Abstract :
This paper presents an online handwritten character recognition system for two major Indic scripts-Bengali and Devanagari. In this proposal, a novel approach for feature extractions is described in which each online stroke information of a character is divided into a number of local zones. For each online stroke information different structural and directional features are extracted separately in each of these local zones. Next, these features are concatenated and fed to SVM classifier for recognition. The character recognition accuracy obtained is 87.48% for Bengali script and 84.10% for Devanagari script on 4900 and 5000 test samples respectively.
