[QUESTION] Treshold parameter

Open pacioc193 opened this issue 2 years ago • 2 comments

Could be possible to explain which is the real working of treshold value?

I'm trying to compare this two image

I can't find some parameter that works always... Do you have any suggestion?

Hi @pacioc193, Threshold value - is a max distance between different pixels in one area. It means, that if we have the next area, which is far away on more than the threshold value, it would be selected as a new area of differences.

Did you create some GUI for comparing?

Yes, I'm developing 6 positions real time status system. In this system I must compare when a oil in water is separate and return to start situation ( left photo )

Algo is working but not always good precision...

Any tips?
