# Sky Segmentation App 🌤️

This is an interactive web application for sky segmentation using a trained U-Net model with ResNet50 encoder.

## Features

- 📁 Easy image upload interface
- 🎭 Real-time sky mask generation  
- 🔵 Visual overlay showing detected sky regions
- 📱 Mobile-friendly responsive design
- ⚡ Fast inference on CPU/GPU

## How to Use

1. Upload an image (JPG, PNG, WEBP supported)
2. The model automatically processes your image
3. View three outputs:
   - Original image
   - Binary sky mask (white = sky)
   - Colored overlay with sky highlighted in blue

## Model Details

- **Architecture**: U-Net with ResNet50 encoder
- **Framework**: PyTorch + Segmentation Models PyTorch
- **Input Size**: 512x512 pixels (automatically resized)
- **Output**: Binary segmentation mask
