Invisible Image Watermarking Tool

A C# application for seamlessly adding and retrieving invisible watermarks in images using advanced pixel manipulation techniques.

🌟 Features

• 🖼️ Add invisible watermarks to single image
• 📁 Process entire directories, including subdirectories
• 🔍 Retrieve and display watermarks from processed images
• 💻 Modern and intuitive user interface powered by Guna UI 2

🔧 How It Works

It employs a sophisticated pixel manipulation technique to embed invisible watermarks:

1. Images are composed of pixels, each with Red, Green, and Blue (RGB) channels.
2. Channel values range from 0 to 255.
3. We embed the watermark by adjusting these channel values:
   • Odd values represent white pixels in the watermark
   • Even values represent black pixels in the watermark
4. These subtle adjustments are imperceptible to the human eye but detectable by application.
