That seems very interesting.
However the objects are moving within a moving stream of sludge. Everything moves.
Also, when I referred to noise I didn't mean video noise, I meant random background artefacts caused by the sludge flow.
Everything is coated in sludge so I can't use colour, everything is the same temp so I can't use IR, nothing is metallic so I can't use electromagnetic detectors.
The only option that is plainly visible is hard edges within a rough surfaced undulating flow of gunge.
Unfortunately I can't show you all what I'm working with - my client would go ape and consider it a total infringement of confidentiality.
So I can only describe the problem.
