[microsound] image sonification techniques

[Jaime Munarriz Ortiz]

I did motion capture at Amsterdam long time ago, body and facial.
You can use ultrareflective material for the dots, and infrared cameras 
to receive a really clean image.
But you don't need a scientific precision: I had great results using 
just the "difference factor" between 2 frames, i.e., the amount of change.
You can read motion from different sections of the image, getting some 
"virtual pads" that can flow to different sound parameters. From them 
you can extract the moving blobs, the amount of certain colors, the 
changes in time... this coul lead to a very expressive system, without 
the scientific precission of motion capture.
