Need some help in java mini project:

ghaniI am doing computer science, currently in 6th semester. I am planning to have a mini project in preferably JAVA or any other related language, this mini project may lead me to my Final Year Project in next year.
My interested areas are Image Processing, AI in gaming and AI in robotics.
Any expert advice please.

Good to have you here. Tell us the ideas you've thought on your own, if any. It would also help to have a look at this section.

Thanx big_K..
i have some ideas like "Model Human Eye Vision System Using Two Movable Cameras", "Automatic Learning Machine with Wikipedia", "Some Fight Game Using Real Human Faces".
I have just rough ideas, I don't how to start and what are the pre-requisites. Also I am confused about their productivity, weather they could help me in Final Year or not.
Any expert advice will be warmly welcomed.
