    Hello,
    I am currently working on a live performance and need to know the folowing:
    How to take values out movement: I am using the jit.op absdiff but can't take any value out of it.
    How to take values out of the image when it's darker or brighter.
    Thanks a lot in advance Egg_White

      I normally pass xy values from jit.iter (left outlet) only if they exceed a threshold (> on center outlet). Assuming you have used jit.rgb2luma to turn the matrix into a single plane. This is daft, but kind what i's talking about:
