Hallo to everybody.

I am working on my master project, and it is about constructing an autonomous wall following and obstacle avoiding robot. To make things little interesting I want to add some sort of camera on the top of the robot-vehicle so that robot can follow certain signs (take a LEFT turn, or take a RIGHT turn or STOP). The sign for left turn would be black left-pointing arrow on white base, for right turn black right-pointing arrow on white base, and for stop black circle on white base. Is there a possibility that PIC or dsPIC can process these images in the real-time? (little delay is tolerant). Has anyone had any experience with something similar. And which type of camera should I get? Cheers!
