Feature extraction strategies for Indian Sign Language Recognition: A Review
Bhavika Patel · International Journal for Research in Applied Science and Engineering Technology · 2018
Sign language is the language used by the general population with hearing and talking disabilities for communication in their day to day life. There are many sign languages such as Indian Sign Language (ISL), American Sign Language (ASL), and Chinese Sign Language (CSL), British Sign Language BSL). More research work is done in ASL side than ISL because ASL uses a single hand for making signs. But ISL is a language which is double-handed sign language so it becomes quite difficult for making recognition system for it. By couple of years researchers from India try to develop ISL recognition systems.There are mainly four stages associated with sign language recognition -image acquisition, preprocessing, feature extraction and classification.
