Online Handwriting Recognition for the Arabic Letter Set

摘要

Automated methods for the recognition of Arabic script are at an early stage compared to their equivalent for the recognition of Latin and Chinese languages, especially of online handwriting recognition. In this paper we describe the stages of the recognition process unique to the Arabic hand written text. We also introduce an account of Arabic online handwriting recognition methods in literature, with a rich list of references for the interested readers. We cast some light on the characteristics of Arabic writing and present an overview of the common stages normally followed by handwriting recognition systems which are: preprocessing, segmentation, feature extraction, classification, and post-processing along with the most used techniques.
