AR masks development

This is a party game, an AR version of "Who Am I" or "Celebrity Heads". You could've seen this game in Inglorious Basterds: the players put a card with a name of a famous person or a character on their forehead and ask yes or no questions of other players to figure out who is the person on their card. In this AR version of the game, you use the camera of your device to look at other players. Instead of the cards, you see the players wearing masks, faces of famous people or fictional characters. The masks work like snapchat filters: face recognition and tracking. Your job will be modelling these masks either based on an premade asset or from scratch.
