Color detection live stream,processing, PCI Win interface

Objectiv: detect colored strings!-not large objects- on a live stream @ 25fps stream, establish their location in order to be ejected, via PCI card/Sol valves at the end of conveyor running at 2.5m/sec Get the live stream from a Firewire (now) camera of of a conveyor carrying mixed color materials. Detect the colored (everything but black, white and grey) and then by applying CannyEdge or similar, then create a skeleton Speed of processing is important! Details ready.
