  21. Affdex – Affdex reads emotional states such as liking and attention from facial expressions using a webcam… to give marketers faster, more accurate insight into consumer response to brands and media.
  22. Faceware – Analyzer takes in a video of an actor’s facial performance and produces an .IMPD file for use in Retargeter™. It accomplishes this through the combination of simple user input on the front end, and complex computer vision algorithms on the back end.
  23. Face detection in iOS
