I’ve been trying to figure this out for three days, but I’m quite new to C++ and I seem to have hit a wall.
I want to change one of the opencv source files, particularly the eigenfaces function written by bytefish. I want to have it return many faces instead of one. I believe I figured this part out.
The problem is that, when I recompile opencv, no matter what dll I use, when compiling the demo facial recognition code, I get a couple errors:
