Abstact: Sign language is a mean of communication among the deaf people. Indian sign language is used by deaf for communication purpose in India. Here in this paper, we have proposed a system using Euclidean distance as a classification technique for recognition of various Signs of Indian sign Language. The system comprises of four parts: Image acquisition ,pre processing, Feature Extraction and Classification. 31 signs including A to Z alphabets & one to five numbers were considered in this paper.

Key words: Sign Language Recognition (SLR),Indian Sign Language (ISL),Principal Component Analysis(PCA)

1. Introduction:

Sign language is the natural ways of exchanging information among the deaf. It has been observed that deaf people are facing difficulty to interact with normal people. The purpose of sign language recognition system is to provide an efficient and accurate system to convert sign language into text so that communication between the deaf and normal people can be more convenient.

Sign language consists of vocabulary of signs in exactly the same way as spoken language consists of a vocabulary of words. Indian sign language (ISL) is sign language used in India. ISL involves both static and dynamic gestures, single as well as double handed gestures, in addition to this the hands involved in gesturing may have complex motion. Some signs include facial expressions too. Because of these...
