## Description
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 💪💪💪

⭐ This video is brought to you by HubSpot! Check out their FREE AI Coding Showdown comparing OpenAI Codex and Claude Code:  


Big thanks to HubSpot for sponsoring this video and providing the guide for free! 🙌

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! 🤩

🚨important note for people who are new to this channel, and never watched my videos before 🚨
- Windows is better than WSL for this specific workflow.
- Native Linux is better than Windows for everything. This workflow included.

Hope it helps! 🫡
