Recently Google had commercials demonstrating that their photos do a better job of accurately photographing people with darker skin tones. IIRC, a professor on Twitter also noted that Zoom’s background blur feature was blurring his Black colleague’s head (presumably because the AI thought it was an object?).
I’ve heard this also difficulty applies to pets like black cats and labs.
So, why are people with darker skin harder to photograph?
