blob tracking

Absolute Simplest Blob Detection on PC with WebCam

Hi There,

We need to know the absolute simplest way to do blob tracking using a windows pc. 

We are building a robot that seeks and collects tennis balls. Everything is working except for the ball recognition. All the PC software has to do is get the x,y coordinates of a yellow blob, and then send the appropriate signal to the COM port (we have 4 values that are sent to the comport to be interpreted by a pic micro and translated into "move forward" "move backward" "turn left" "turn right")
