there is no delphi wrapper. In c++ you can use > and countnonzero

I use: cvMinMaxLoc (image, @minval, @maxval, minloc, maxloc);   to find @maxval coordinates, but I want to count how many pixels are brighter than the RGB color 80:80:80.

OpenCV is completely incomprehensible to me, so I am asking for a ready example. ;)

@mpknap, please do not try like that.

your delphi wrappers use the since long defunkt opencv1.0 c-api, and the devs are removing it, piece by piece now.

please try with c++ or python / java wrappers, NOT delphi.

Thanks for explaining. Or maybe you will provide this instruction in C ++? I will try to translate it myself ...
