Sign language is widely used by individuals with hearing impairment to communicate with each other conveniently using hand gestures. However, non-sign-language speakers find it very difficult to communicate with those with speech or hearing impairment since it interpreters are not readily available at all times. Many countries have their own sign language, such as American Sign Language (ASL) which...
Nowadays, hand gesture is one of main considerations for hearing impaired people because they use sign language to communicate with each other and to normal people. In general, the normal people have difficulties with sign language therefore they need an interpreter supporting communication. Then the automatic hand gesture recognition system is needed to help hearing impaired people integrating into...
Sign language detection and recognition (SLDR) using computer vision is a very challenging task. In respect to Bangladesh, sign language users are around 2.4 million [16]. In this paper, we try to focus for communicating with those users by computer vision. In this respect, an efficient method is proposed consists of some significant steps and they are, skin detection, preprocessing, different machine...
The Sign Language is a method of communication for deaf-dumb people. This paper presents the Sign Language Recognition system capable of recognizing 26 gestures from the Indian Sign Language by using MATLAB. The proposed system having four modules such as: pre-processing and hand segmentation, feature extraction, sign recognition and sign to text and voice conversion. Segmentation is done by using...
Sign language data can be expressed as the positional changes of hands over time. Although increasing the number of hand movement sensors increases the recognition rate, the data scales become larger. In addition, each sign language data has a different duration. When large data are generated continuously, lower memory usage and a standardized form of data are necessary to be applied immediately in...
During recent years a large number of computer aided applications have been developed to help the disabled people. This has improved the communication between the able and the hearing impaired community. An intelligent signed alphabet recognizer can work as an aiding agent to translate the signs to words (and also sentences) and vice versa. To achieve this goal few steps to be followed, among which...
