Image Classification Techniques 🌟

Image classification is a fundamental task in computer vision, aiming to categorize images into predefined classes. Here are key techniques and concepts:

1. Traditional Methods 🧠

• Histograms & Color Features 🎨
  • Use color distribution (e.g., RGB histograms) to identify patterns.
  •
