Maybe someone can enlighten me. I first heard about this problem 10 years ago. I'm sure it's been known far longer.

Is there some extremely difficult algorithmic problem preventing these systems from working on people with darker skin?

I had presumed it was a long corrected oversight but it still appears to be a problem.

Even photographic cameras have difficulty with exposure for dark skin. This is a problem as old as photography.

So the deltas are narrower creating a breakdown in the SNR for say edge detection?

Please excuse me if this is totally wrong and I sound ignorant, I assure you I am...
