# Face Landmarks

Face landmark detection relies on the open-source project, [Media Pipe](https://ai.google.dev/edge/mediapipe/solutions/guide). They provide AI/ML models that run on-device to analyze live video frames. This feature of the platform uses face landmark detection to calculate scores (coefficients corresponding to different expressions) of 52 locations across the face.
