Project Details
How It Works
How It WorksThe ESP32-CAM uses the ESP-WHO AI framework to perform face detection and recognition. First, it detects faces in the camera feed. Then, it extracts facial features (landmarks, embeddings) from the detected face. These features are compared against stored profiles of registered individuals. If a match is found above a certain threshold, the system identifies the person. All processing happens locally on the ESP32-CAM's processor, ensuring real-time performance and privacy. The system can be accessed via a web browser to enroll new faces and view recognition results.
Prerequisites
Basic knowledge of Arduino programming, familiarity with ESP32 boards, understanding of basic electronics and wiring, and experience with web interfaces. Users should also understand the concepts of AI and computer vision at a beginner level.
