Brilluant! They have managed to build an algorithm that is both inaccurate and racist at the same time. You could not make this stuff up!
but also with a DSLR it's harder to calibrate the correct exposure with dark skinned subjects, i don't think these face-recognition algos will become perfect, if the face is dark and they dress dark but the rest of the photo is bright there's just too much contrast especially if their face is in shadow.
