Completely working though maybe not much more than a first step towards

your specifications:
http://lapoc.de/spinoffs/stromchello.ams
a patch for Alsa Modular Synth that sounds quite a bit like a cello.

Please take into consideration, that I do not believe in synths that

emulate real instruments. It is a synth clearly recognizable as a synth

that has some charakteristics that give it the feel of a cello-sound.
There are some more experiments like this in the directory:

cool ;-)
I do not know any method that could make ams recognize the difference

between up/down-stroke.
But there is hope: the most simple way to have an up/downstroke

separation would be 2 instances of ams with properly tweaked patches.

OK, now I get it: you want a cello played like a teremin.
This one is easy once you have the movements as

MIDI-controller/note-messages.
Anyway you do not really need notes. It should be only one Note that

triggers the sound regardless to pitch. Velocity and/or volume raising

from left to right should not be that hard to achieve.
The other hand could control the pitch-parameter.
I do not know how you would create the messages-data from the

camera-pictures. But I can tell that it is a piece-of-cake operation to

bind them to parameters in AMS once you have them.
good luck an dkeep us up to date :-)
