A Recent Overview on Usage of Indian Sign Language

International Journal of Computer Science (IJCS) Published by SK Research Group of Companies (SKRGC)

Abstract

A system to recognize static gestures representing the words has been placed onto the system. The recognition of handmade gestures in certain sequence of image enables a human-computer interaction applications. Human Computer Interaction moves forward in the field of sign language interpretation. Indian Sign Language (ISL) Interpretation system is a good way to help the Indian hearing impaired people to interact with normal people with the help of computer. Vision based hand gesture recognition system have been discussed as hand plays vital communication mode. This work consist of three phases. First phase is pre-processing, in which images are processed through some steps such as reducing distortion and greyscale conversion. Greyscale image is taken so that it shapes and then descriptors can be applied easily to extract the required features.
