for an installation i want to use jitter, colour tracking.
i will sprinkle lucent green drops (fluorescein – glows in uv-light) on a glass table and detect them with a camera. to do so i think i will part the image in probably 80×60 cells.
what i do need now is each cell to tell me if there’s green colour in it or not. i basiclly need to know the number of the cell and if the cell is active or not – 1 or 0. further i need this data to control sound parameters in maxmsp.
so, what jitter object do i need to get this data?
thanks for all answers in advance!!
Another idea would be to "downsample" your matrix, take just the green plane, and use jit.op @op > @value (threshold) to get a small matrix giving you 1/0 for each of your "cells" (by the way, a "cell" in jitter is something specific, not the kind of area you describe). Then, you can do many things to drive sound processing with that (as long as you have a MSP patch working, it won’t be hard to hook the jitter analysis to your sound synthesis or processing parameters).
