Hi,

I am new for matlab , as per my requirement i have implement lip key points like left ,right,upper ,bottom and centroid .with reference link http://www.mathworks.in/matlabcentral/answers/54610 after that how calculate threshold for lip reading .

example : If I Silent Spell word Hello with the help of boundary lip key points how to track threshold match known template?

Best example let me know .Thanks

T_Sum_Pixel = sum(bw_videoFrame1);
     bw_threshold = 350000;
     if T_Sum_Pixel > bw_threshold

Sorry, I just don't have time to get the paper, read and understand it, code it up, and explain it to you. I don't even have time to try all the things I'm interested in, much less for anyone else. Good luck though. You'll probably learn more doing it yourself anyway.
