🖼️ Image Compression & Decompression

📰 Description

A MATLAB-based image compression and decompression tool implementing two powerful algorithms:

• DCT (Discrete Cosine Transform): Fourier-Transform based algorithm for lossy compression
• Huffman Encoding: Provides lossless data compression with adaptable input format support

The GUI allows an image to be loaded, displayed, compressed, decompressed, and saved according to user interaction.

🏗️ Implementation Details

File Structure

• Dashboard.m: Main script containing GUI code
• Dashboard.fig: GUI display file
• comp.m: Compression implementation
• decomp.m: Decompression implementation

Error Handling

The application includes comprehensive error handling:

• Enforced operation sequence (Load → Compress/Decompress → Save)
• Warning messages for incorrect operation order
• Graceful handling of cancelled operations
• User-friendly error messages

🛠 Initialization & Setup

# Clone the repository
git clone https://github.com/pedroandreou/ImageCompDecomp.git

🚀 Building and Running

Two options to run the application:

1. Run Dashboard.m file in MATLAB IDE
2. Double-click Dashboard.fig to display the GUI directly
