Deforestation Analysis using Color Segmentation

✨ Created with ❤️ by Heleena Robert

---

🏞 Overview

Deforestation Analysis is a simple computer vision project that uses color segmentation to analyze vegetation cover in satellite or aerial images.
It highlights green areas, calculates the percentage of vegetation coverage, and visualizes pixel distribution using BGR and HSV histograms.
This tool is ideal for tracking deforestation trends or comparing forest cover across different time periods.
By automating segmentation and analysis, it provides an easy way to visualize environmental changes over time.

✨ Features

• Vegetation Segmentation: Detects green regions using HSV color thresholds.
• Green Coverage Calculation: Computes % of vegetation pixels.
• Histogram Analysis: Plots BGR and HSV histograms for vegetation trends.
• Automated Output Saving: Saves segmented results and histograms in output/.
• Visual Comparison: Displays original vs segmented images side-by-side.

🚀 How It Works

1. Place your forest or aerial images into the input/ folder.
2. Run the script to process all images.
3. View results in the console and check output/ for segmented vegetation maps and histograms.
