Python Face Detection from Scratch (OpenCV + YOLO + Webcam)
Face detection has been watching you for years. Every time you unlock your phone, walk through an airport, or enter a store with security cameras, a computer is trying to find your face. 👀 Today, it's your turn! Instead of being detected, you'll become the detector 💪💪💪

In this beginner-friendly tutorial, we'll build a real-time face detection system from scratch using Python, OpenCV, and YOLO. Along the way, you'll learn how to detect many other objects in images and real-time video streams. We'll even combine multiple YOLO AI models to detect different things all at once! 🤩
📚 What you'll learn 📚
How OpenCV reads images and video streams from different cameras
Installing and using Ultralytics YOLO
Detecting faces and objects in real time
Setting up and using community-trained YOLO models
Running multiple YOLO models on the same image or video feed
Running your YOLO workflows on GPU for maximum performance
