[ANSWERED] Make a good Black & White mask from a not so contrasty video feed


  • Hello community,

    I use a lot of live B&W alpha mask to do mapping of moving objects.

    I take the IR camera feed, contract it to make a mask out of it, mask that I use to project directly on the object.

    I use to have a nice Max patch do to the mask, that I feed in Isadora in syphon, but I'd like to do it now directly in Isadora to loose part of the latency.

    So far I get this (original IR cam > result): 


    with this few actors:


    I'd like to get to this kind of contrast:


    Any Idea, possibly staying with vid-gpu actors ?

    Thank you for your inputs, Best,

    The Threshold actor could work. I can’t recall if it is gpu video module.
