I was playing with your demo page and was curious, how do you handle gender classification? Follow-up would be what are you results in broad ethnicity recognition (based on what I've seen, I can tell you at least tried it). Any attempts into age?

Thanks for testing our api.

We have trained our system so that it knows typical/common female and male facial features.

Our machine learning algorithm will generate a score from 0.0 to1.0 representing gender.

We are still tuning our age and emotion recognition. We will release (most likely in just a couple of weeks) it when we feel it's good and reliable enough for public use.

It's great to see a service like ReKognition offering a Face Recognition API in the wake of Face.com closure. Keep on doing what you're doing!

It's really encouraging to hear you saying so! Also, we will launch age detection and FB training API soon. Your feedback is always welcome.
