Detailed Documentation

This is a MATLAB-based source code package for conducting image watermarking attack experiments. The program enables researchers to implement watermark embedding algorithms and perform various attacks to evaluate watermark robustness and security. Key features include implementations of spatial-domain and frequency-domain watermarking techniques using MATLAB's Image Processing Toolbox functions like imread(), imwrite(), and dct2(). The code structure supports testing common attacks such as noise addition, filtering, compression, and geometric transformations through customizable parameters. Researchers can modify embedding strength parameters, apply different transformation algorithms (DCT, DWT), and analyze PSNR/NC metrics to study watermark survivability under various conditions. This source code provides a flexible framework for understanding digital watermarking principles and conducting comparative studies of different watermarking schemes.
