How to Auto-Crop Objects with YOLOv11 and Python

Automate Your Dataset Creation with YOLO & Python! 🚀 Tired of manually cropping images for your machine learning models? In this tutorial, we’re diving into a professional-grade Python script that uses YOLO and OpenCV to automatically detect, crop, and save specific objects from any video file. Whether you are a researcher building a custom dataset or a developer looking to automate image processing, this workflow is a game-changer. We'll walk through the Crop-Object.py script step-by-step, showing you how to filter by COCO class IDs and save high-quality crops instantly. 🔍 What You’ll Learn: ✅ How to set up Ultralytics YOLO for object detection. ✅ Filtering specific objects (like motorcycles) using Class IDs. ✅ Using OpenCV to handle video streams and frame manipulation. ✅ Automating the image saving process for dataset preparation.
