Hiya.
I tried "pictriev" out more than a year ago (im fairly sure it was pictriev), and was very disappointed with the results...
So, just for fun, I recently tried it again, after 10mnths HRT, and now get between 80-90% female.
Just out of curiosity, I tried photos of me just before HRT, and various stages during transition, and noticed the percentage going up as time went by. (very noticeable from about 6 months)
I had an ID photos taken several months ago, and ones recently, which I personally cannot see much of a difference between them, but the software reveals a huge difference.
Again, what I see, and what others see, also seems totally different... Friends and family have mentioned face changes, but cannot point anything out to me.
BTW, a wig does not really make a big difference, it shill showed 9x% male pre HRT.
I'm curious what the software actually focuses on, to determine gender.
