Analysing Live Video

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

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:
