MagniSnap

Project Description

MagniSnap is a C# Windows Forms application designed as a startup project for implementing image processing algorithms, specifically focusing on the Intelligent Scissors (also known as Livewire) technique for image segmentation.

This project provides a basic framework for loading, displaying, and processing images, along with utility functions for pixel manipulation and energy calculation.

Features

• Image Loading & Display: Open images from the file system and display them in the application window.
• Image Information: View image width, height, and current mouse coordinates.
• Image Processing Toolkit:
  • Gaussian Smoothing: Apply Gaussian filters to smooth images and reduce noise.
  • Edge Energy Calculation: Compute gradient magnitudes and edge energies, essential for the Intelligent Scissors algorithm.
• Interactive Tools:
  • Livewire Tool: A placeholder for the Intelligent Scissors tool, allowing for interactive segmentation (to be implemented).

Project Structure

• MagniSnap/: Contains the source code for the application.
  • mainForm.cs: The main entry point for the UI, handling user interactions and events.
  • ImageToolkit.cs: A library of static functions for image processing, including:
    • OpenImage: Loads an image into a 2D RGB pixel array.
    • ViewImage: Renders the pixel array to a PictureBox.
    • GaussianFilter1D: Implements Gaussian smoothing.
    • CalculatePixelEnergies: Computes edge energy for graph-based segmentation.

Getting Started

Prerequisites

• Visual Studio (2019 or later recommended)
• .NET Framework

Installation & Usage

1. Clone the repository or download the source code.
2. Open the solution file MagniSnap.sln located in Project Description & Template/MagniSnap Startup Code/[TEMPLATE] MagniSnap/.
3. Build the solution to restore dependencies.
4. Run the application.
5. Use the File > Open menu to load an image.
6. Select the Livewire tool to test the segmentation features (once implemented).
