Sakshi Sharma, Sukhwinder Singh
Abstract
Communication is an essential activity for a human being to express their feeling, ideas, work together, and for the overall development of society. A person with a hearing disability uses sign language for communication and this language develops naturally within them. However, it is not commonly understood by non-signer community and hence, there remains a communication gap between these two communities. To bridge this gap, a computer vision based recognition system can be used. Many researchers have been worked on this field to facilitate the ease of communication between these two communities. In this paper, the basic concept of sign language recognition system and review of its existing techniques along with their comparison presented. The main objective of presenting this survey is to highlight the importance of vision based method with a specific focus on sign language.
