YOLOv8 & OpenCV Learning Repository

Overview

This repository documents my hands-on learning process in computer vision, focusing on:

  • YOLOv8 — object detection workflows, parameter exploration, and result analysis
  • OpenCV — fundamental image processing techniques and experiments

It combines code, notes, datasets, and generated artifacts to form a reproducible learning pipeline.
