2. June 12, 2016 CITALA'12 2 Introduction and Motivation (1/3) : Optical Character Recognition (OCR) system is a process which allows computers to recognize written or printed characters such as numbers or letters and change them into a form that can be used by the computer. Optical Character Recognition (OCR) system is a process which allows computers to recognize written or printed characters such as numbers or letters and change them into a form that can be used by the computer. There are many OCR system in use based on different algorithms. All of the popular OCR support high accuracy and most high speed, But till now, Arabic handwriting recognition systems have been limited to small and medium size of documents to recognize. But till now, Arabic handwriting recognition systems have been limited to small and medium size of documents to recognize.

3. June 12, 2016 CITALA'12 3 Introduction and Motivation (2/3) : Other motivation, we need a technology that offers a number of benefits, such as the ability to store and retrieve large amounts of documents in a pervasive environment).

4. June 12, 2016 CITALA'12 4 Introduction and Motivation (3/3) : For that, it is necessary of technologies more «Efficient» The concept of efficiency suggests that it is necessary to choose an efficient storage infrastructure to decrease the whole of its exploitation costs and satisfy other exigencies of large scale application in a pervasive environment. We propose a new approach to distribute the Arabic handwriting OCR system based on cloud computing technologies.

7. June 12, 2016 WDI 09 7 Problem statement (1/3) Many national libraries and archive centers are still in the form of newspaper, books, magazines, research papers, conference proceedings, dissertations, and monographs. Indeed, the complex morphology and the cursive aspect of this writing are behind the weakness of the proposed approaches. The project is expected to be connect with vanguard digital libraries such as Google, and digitize many books, periodicals and manuscripts.

8. June 12, 2016 WDI 09 8 Problem statement (2/3) Different Arabic words are recognized sequentially on a PC (3.4 GHZ CPU frequency, 1GB of RAM and running Windows XP-professional).

9. June 12, 2016 WDI 09 9 Problem statement (3/3) Therefore, it is necessary to build a strong application to shorten the used time and increase the throughput. Consequently, we can conclude that large scale OCR system requires enough computing power and storage. This is possible using distributed system such as Cloud Computing.
