Nice overview. Too bad the test set was rather tiny (33 images). Detection rates in this test:

  Amazon    52.66 % 
  Google    40.43 %
  IBM       39.36 % 
  Microsoft 17.55 %

just for comparison, I used this open source library (https://github.com/ageitgey/face_recognition) on the dataset and even with the cpu model (according to the github page the CNN is more accurate, but I couldn't test it out right now) it identified 59/188 faces.

I'm wondering what's up with the Microsoft result. Some sort of error in processing the images?
