ARKit/MLKit Face Detection based virtual lipstick.

Requires iPhone X/XR/XS/XS Max, iPad Pro (11-inch), iPad Pro (12.9-inch, 3rd generation), or other iOS devices with front-facing TrueDepth camera running iOS 11.0 or later.

Mainly based on Apple’s sample code Tracking and Visualizing Faces. Support for multiple faces is not yet verified, but it should work (I hope).

I modified the original wireframe to only mask where the lips are, but it’s not very precise. Here’s the preview of the full size wireframe texture for you to make your own, probably more precise mask:

For other devices not having ARKit face detector, we'll use MLKit to trace facial contours, like this:

I highly recommend checking out the official documentation for more instructions.

I tried the Apple provided Vision.framekwork, but it can only generate a LOW QUALITY outline for lips. It's not suitable for the purpose of this app, but if you are interested in using it for some other features, see VNFaceLandmarks2D for details.

List of lipstick colors (and their names/brands in Chinese) are from Ovilia/lipstick.

I never figured out how and if grizzly3ear/lipster-mobile works, but it does point me to Vision.framework and FirebaseMLVision (predecessor of MLKit Face Detection).
