Yo, facial recognition is utter bullshit at times. This "person" has been recognized by my NAS. Still cannot figure out, which of my relatives this hit resembles most...
I took photos at a friend’s wedding and most of the photos of his new wife had her wearing a lace veil.
I dumped all the photos into Picasso (precursor to Google Photos) and it did its background facial ID on everything. Then it suggested more photos that might also be tagged as her.
The extra photos were all just tables with tablecloths on them. It thought she was a tablecloth.
I purposely take awful photos from time to time and I didn’t realize I could set the key photo in Apple’s Photos app. Without fail it chose the absolute worst photos of people to the point I cracked up for several hours after seeing the People albums it generated.
