Real-Time Face Tracking in the Browser with MediaPipe

MediaPipe enables real-time face tracking directly in browsers without servers or cloud infrastructure. The tutorial demonstrates building a face filter application using MediaPipe's Face Landmarker to detect facial landmarks and overlay animated elements like monkey ears. The implementation uses WebAssembly for performance, GPU acceleration for inference, and canvas manipulation for real-time video effects. The approach offers zero latency, complete privacy, and full UI control while supporting up to two faces simultaneously.
