Using video input in Squeak

I'm not sure who has been following my story, but I started this project
using a Mac, and then switched to a PC running Windows (at the urging of
my mentor).

I am using the DVideoShowDecoderPlugin. I have tested it, and it works.
My next step is separating the live actor's shadow part of the video
image from the white background: I need to convert the Form from color
to black and white. Once I have the shadow only, I can make a Morph out
of it and instruct the virtual balls to react to it.

Does anyone have any tips on the easiest way to convert the color image
to B/W?

You would have to write a plugin similar to Diego's V4LPlugin that uses 
Quicktime to read from the camera. To my knowledge, there is no such 
plugin, yet. It might be a good idea to use the same primitives to 
minimize platform-dependencies on the image side.
