Thriving efforts in the area of Sign Language Recognition (SLR) research within the last few decades makes a good interaction between human and computer system. Sign Language is basically a means for dissemination through signing which, utilizes specific sign patterns performed to deliver the meaning with the use of hands, lips and facial expressions to conveniently be able to express the signer’s thoughts. The process involves the concurrent association of the shape of hands, the position of the body posture and also the facial expressions.
