Abstract. Communication is an essential factor for the global social interaction of individuals. There are several forms of communication, among them we have the Brazilian Sign Language, a gestural language, whose main objective is to enable the inclusion of deaf people in society. Sign Language is visual and ges- tural, so its possible to affirm that the use of technology, together with Computer Vision techniques, can contribute to the inclusion of deaf people in society. This paper describes the development of a Computer Vision software that, through the use of digital image processing techniques, performs the recognition of ges- tures of LIBRAS alphabet, allowing its comprehension by people who do not have knowledge of that language.
