Great notebook! I just got 55 faces on Sgt. Pepper. Some seem to be repeated (the tour moves just a tiny bit on what I see as the same face).

Thanks! I've noticed some similar issues. Note that I set the minConfidence parameter to 0.4 in the facial detection, which is below the default of 0.5. I'm definitely not an expert in face-api, though! I'm pretty happy with how it works, overall, though.
