I'd recommend doing some benchmarks on these platforms before making a recommendation. The Pi, while a cool board for the price, is pretty underpowered for this kind of task. I was only able to pull about 10 FPS off a Logitech webcam using the Pi using OpenCV without doing any image analysis. I was using the Python bindings so there is probably some performance to be claimed by nixing the interpreter and compiling some C, but I don't think it will be much.
