facelivenessdetection #

A real-time facial verification feature using Google ML Kit for liveliness detection. It ensures user interaction through smiling, blinking, and head movements. Features include face detection, dynamic feedback, a countdown timer, and customizable UI—ideal for secure authentication and anti-spoofing verification. 🚀
