need help of dessertation thessis on video processing

hello all..
as being a ME students , i have to go for research work..for that i m planning to go for video processing..
so need idea how and in what direction i should go...!
please help..

I have believed (and experienced it myself) that the purpose of "dissertation thesis" is to make a candidate study and work as hard as possible. This work should prove you are ready to solve real problems.
My advice therefore is: GO AND STUDY HARD, AND WORK EVEN HARDER!

Asking others to solve your problem is quite mean, don't you think?!
