Mobile Optimized Face Detection

via “on-device face detection with multi-face tracking”

Google's cross-platform on-device ML framework with pre-built solutions.

Unique: Uses Google's proprietary lightweight face detection model optimized for mobile inference with hardware acceleration (GPU/NPU) on Android, iOS, and Web via native platform APIs, rather than generic computer vision libraries; includes built-in multi-face tracking across frames without requiring external tracking logic.

vs others: Faster and more accurate than OpenCV's Haar Cascade face detector on mobile devices due to neural network-based approach, and requires no cloud infrastructure unlike cloud-based face detection APIs, but less feature-rich than specialized face recognition systems like FaceNet or ArcFace.
