| The work described in this master thesis is part of a bigger project, which aims at the digitizing of Braille documents and publishing them on the Internet. The project was developed in the Scribens laboratory with the help of different external sponsors.; Our project aims at the numerisation of Braille documents in order to insure their conservation, reproduction and diffusion on the Internet. A commercial scanner is used to obtain an image of a Braille page. This page then becomes input for the Braille optical characters recognition module, which outputs the corresponding ASCII text. Taking into account the documents' age, their wearing, the obsolete printing technique and the quality of the support, it is realistic to assume that the resulting text will not be error prone. As a consequence tools must be used to edit the text produced by the Braille characters recognition module.; We should emphasize the importance of this project in terms of promoting the Francophone culture. The emergence of global communication nets creates a challenge for every culture to ensure its visibility and survival in this new environment for information stoking and diffusion—Internet.
