Indian Sign Language Recognition Indian Sign language Recognition: This is a first step towards designing a system for deaf and dumb. You must have seen people talking in sign language, they can only communicate with one who understand language of sign. Everybody do not understand signs, So we need a system which will generate voice after recognizing the signs. This will be one of the noble work by which these people will not feel isolated, They will not hesitate going around and enjoying the life, they will not miss a chance to talk any body just because they can not talk. Here we have implemented our initial work on MATLAB and results are recorded and shown in video. Paper is published and is available at IEEExplore you can find paper here : Go to Paper Full screen video on youtube Fractal Art in Signal Processing for Fashion Fractal Art in Signal Processing This is one of the very fascinating work. There are many fractal equations available for generating different patterns. We also derived some new equations for generating different and beautiful patterns. Some of the Pattern generated are shown in figure. We further tried to use these pattern for designing clothes. Here ‘Design’ means not deciding the pattern, shape and outline of any dress but to putting different patterns on dress in different ways Elementary paper is published and available in IEEExplore: Link Other detail paper is in process. Go to Paper Expression Recognition Description: Facial Expression Recognition Paper is available at Link This paper does not contain very good detail of work, another paper is in process which will have all the details Enhancement of A5/1: GSM Encryption technique Enhancement of A5/1: using variable feedback polynomial of LFSR In this paper enhancement of A5/1 Encryption technique is proposed. Same was simulated in MATLAB and tested with NIST Test suit for randomness.
