True, as long as you can process faster then the camera sends images. We couldn't get the axis camera to send less then 15 FPS, so it would actually start lagging and getting further and further behind as more images came in. And we couldn't figure out a way to make opencv flush the buffer up to the last image.

Also how is the RoboRIO (dual core ~700 Mhz Armv7) much faster then a Pi 2 (quad core 1000 Mhz Armv7)?
