A Deep Learning Approach for Handwritten Arabic Names Recognition

Mohamed Elhafiz Mustafa, Murtada Khalafallah
2020 International Journal of Advanced Computer Science and Applications  
A holistic recognizer that recognizes common words directly (without segmentation) seems the plausible model for recognizing Arabic common words.  ...  Therefore, traditionally Arabic recognition systems segment a word to characters first before recognizing its characters.  ...  However, publication on word recognition are few with low recognition accuracy rate [15] , [16] . This low rate for word recognition accuracy is mainly due to the error in segmentation [1] .  ...
