Introduction While developing the mediapipe_face_mesh package, I had a chance to dig into MediaPipe’s Face Geometry module. The Face Mesh model outputs 468 facial landmarks in screen coordinates. But screen coordinates alone are not enough to anchor an AR filter onto a face or compute head orientation. What you need is a pose transform matrix that answers: “where in 3D space, and in what orie...

Basic Concepts Spatial Resolution Spatial resolution refers to the minimum distance at which two nearby points can still be distinguished as separate points. For example, if the spatial resolution is: 10 μm, two points at least about 10 μm apart can be distinguished. 1 μm, two points at least about 1 μm...
