This technique is a good alternative to entering text, the availability of various tools involved in the singularity of this service. Undoubtedly, the development of such tools will provide a considerable gain in time and costs. The basis of the Arabic language, prompted us to work hard for a successful control of its optical character recognition, otherwise it is necessary to develop another approaches, therefore an approach based on finding a word-image in a textimage.
