# 🔺 Geometric Shape Detection

An intelligent computer vision application that automatically detects and classifies geometric shapes in images using advanced OpenCV algorithms and an intuitive Gradio interface.

## 🚀 Try It Out

Upload any image containing geometric shapes and watch as the AI identifies:
- **Triangles** (3 vertices)
- **Squares** (4 vertices, equal sides)  
- **Rectangles** (4 vertices, different sides)
- **Circles** (curved shapes with >6 approximated vertices)

## ✨ Key Features

- 🎯 **Instant Detection**: Real-time shape identification upon image upload
- 📊 **Detailed Analytics**: Get shape count, area measurements, and coordinates
- 🎨 **Visual Annotations**: Clear highlighting of detected shapes with labels
- 📱 **Mobile Friendly**: Responsive design that works on all devices
- ⚡ **Fast Processing**: Optimized OpenCV algorithms for quick results

## 🛠️ How It Works

The application uses a sophisticated computer vision pipeline:

1. **Preprocessing**: Converts to grayscale and applies Gaussian blur for noise reduction
2. **Edge Detection**: Canny algorithm identifies shape boundaries (thresholds: 50-150)
3. **Contour Analysis**: Finds and filters significant contours (minimum 500px² area)
4. **Shape Classification**: Analyzes vertex count and aspect ratios:
