Since the worldwide spread of internet-connected devices and rapid advances made in Internet of Things(IoT)systems,much research has been done in using machine learning methods to recognize IoT sensors *** is particularly the case for optical character recognition of handwritten *** text in images has several useful applications,including content-based image retrieval,searching and document *** Arabic language is one of the mostly used tongues in the ***,Arabic text recognition in imagery is still very much in the nascent stage,especially handwritten *** is mainly due to the language complexities,different writing styles,variations in the shape of characters,diacritics,and connected nature of Arabic *** this paper,two deep learning models were *** first model was based on a sequence-to-sequence recognition,while the second model was based on a fully convolution *** measure the performance of these models,a new dataset,called QTID(Quran Text Image Dataset)was *** is the first Arabic dataset that includes Arabic *** consists of 309,720 different 192×64 annotated Arabic word images,which comprise 2,494,428 characters in total taken from the Holy *** annotated images in the dataset were randomly divided into 90%,5%,and 5%sets for training,validation,and testing purposes,*** models were set up to recognize the Arabic Othmani font in the *** results show that the proposed methods achieve state-of-the-art ***,the proposed models surpass expectations in terms of character recognition rate,F1-score,average precision,and recall *** are superior to the best Arabic text recognition engines like Tesseract and ABBYY FineReader.
