as trajectory chronology, velocity, pressure and pen up/down movements. Their
offline counterparts consist of a set of pixels. Thus, online handwriting recognition
accuracy is generally better than offline. In this paper, we propose an original framework for recovering temporal order and pen velocity from offline
multi-lingual handwriting. Our framework is based on an integrated
sequence-to-sequence attention model. The proposed system involves extracting a
hidden representation from an image using a Convolutional Neural Network (CNN)
and a Bidirectional Gated Recurrent Unit (BGRU), and decoding the encoded vectors to generate dynamic information using a BGRU with temporal attention.
We validate our framework using an online recognition system applied to a
benchmark Latin, Arabic and Indian On/Off dual-handwriting character database.
The performance of the proposed multi-lingual system is demonstrated through a
low error rate of point coordinates and high accuracy system rate.
