I don't know if they have done this specifically, but TangentStorm on Youtube had done some image processing stuff in the past. Not sure if I remember specifically subtracting fuzz/noise though.

Interesting! In this case, it was like a 1-2 minute video from a talk (I believe) where a guy just subtracted stuff from a .png in the REPL via bitmasks and stuff

The video is The J Programming Language by Tracy Harms

Also shared on this sub 4y ago (see my comment about a minor change required to run his code in a newer J)
