Convolutional Arabic Handwriting Recognition System Based BLSTM-CTC Using WBS Decoder
Keywords:
Arabic handwriting recognition (AHR), Bi-Dimensional Long Short-Term Memory (BLSTM), Convolutional Neural Networks (CNN), Connectionist Temporal Classification (CTC), Word Beam Search (WBS)Abstract
Arabic handwriting recognition (AHR) poses major challenges for pattern recognition due to the cursive script and visual similarity of Arabic characters. While deep learning demonstrates promise, architectural enhancements may further improve performance. This study presents an offline AHR approach using a convolutional neural network (CNN) with bidirectional long short-term memory (BLSTM) and connectionist temporal classification (CTC). By enhancing temporal modelling and context representations without segmentation requirements, this BLSTM-CTC-CNN framework with an integrated Word Beam Search (WBS) decoder achieved 94.58% accuracy on the IFN/ENIT database. Results highlight improved efficiency over prior works. This demonstrates continued advancement in sophisticated deep learning techniques for accurate AHR through specialized modelling of Arabic script cursive properties and decoding constraints. This research represents an advancement in the continuous development of progressively intricate and precise systems for handwriting recognition.
