Training an Arabic handwriting recognizer without a handwritten training data set

摘要

Handwritten text recognition is an active research area in pattern recognition. One of the prerequisites of setting up a handwritten text recognizer is to train them using, mostly, large amounts of labeled training data. In the current paper we report our work on handwritten text recognition using no handwritten training set. We investigate different approaches including, computer generated text in different typefaces as training data, unsupervised adaptation, and using recognition hypothesis on the test sets as training data. Results from handwritten Arabic word recognition task show that the approach is promising with good recognition rates.
