An Arabic Optical Braille Recognition System

Technology has shown great promise in providing access to textual information for visually impaired people. Optical Braille Recognition (OBR) allows people with visual impairments to read volumes of typewritten documents with the help of flatbed scanners and OBR software. This project looks at developing a system to recognize an image of embossed Arabic Braille and then convert it to text. It particularly aims to build fully functional Optical Arabic Braille Recognition system. It has two main tasks, first is to recognize printed Braille cells, and second is to convert them to regular text. Converting Braille to text is not simply a one to one mapping, because one cell may represent one symbol (alphabet letter, digit, or special character), two or more symbols, or part of a symbol. Moreover, multiple cells may represent a single symbol

Saudi Accented Arabic Voice Bank

AbstractThe aim of this paper is to present an Arabic speech database that represents Arabic native speakers from all the cities of Saudi Arabia. The database is called the Saudi Accented Arabic Voice Bank (SAAVB). Preparing the prompt sheets, selecting the right speakers and transcribing their speech are some of the challenges that faced the project team. The procedures that meet these challenges are highlighted. SAAVB consists of 1033 speakers speak in Modern Standard Arabic with a Saudi accent. The SAAVB content is analyzed and the results are illustrated. The content was verified internally and externally by IBM Cairo and can be used to train speech engines such as automatic speech recognition and speaker verification systems

Mubser: A Bilingual Braille to Text Translation with an Arabic Interface

The purpose of this paper is to describe the development of a system called Mubser to translate Arabic and English Braille into normal text. The system can automatically detect the source language and the Braille grade

Impact of orthodontic treatment on the integrity of endodontically treated teeth

AIM: The purpose of this study was to evaluate the periapical status of endodontically treated teeth and the integrity of endodontic treatment before and after orthodontic treatment. MATERIALS AND METHODS: This retrospective study was conducted by evaluating 128 teeth with root canal treatment (RCT). The teeth were obtained from 72 patients (23 males, 49 females) who had undergone fixed orthodontic treatment. Panoramic radiographs were taken and were evaluated before the start and after the completion of orthodontic treatment. Apical periodontitis (AP) was evaluated by the periapical index (PAI) and the probability index (PRI) of periapical bone destruction. Other variables related to the quality of root canal fillings were included, such as RCT quality index, length, and homogeneity, and coronal restoration. RESULTS: According to the PRI, the proportion of teeth with periapical bone destruction was significantly higher after orthodontic treatment. Overall, there was no significant change in the PAI scores after orthodontic treatment. However, the quality of the endodontic treatment moderated the change in the PAI score, as well as the change in the PRI. There was no significant increase in PAI and PRI scores after orthodontic treatment for adequately treated teeth. However, the risk for periapical lesions and bone destruction after orthodontic treatment was significantly increased for teeth receiving inadequate endodontic treatment compared with those receiving adequate endodontic treatment. CONCLUSION: Increased PAI and PRI after orthodontic treatment correlated with the quality of endodontic treatment.status: publishe
