Digital Watermarking Implementation Using DWT (Discrete Wavelet Transform)

This implementation demonstrates digital watermarking using Discrete Wavelet Transform (DWT) methodology, featuring comprehensive code comments for developer clarity and understanding of the underlying algorithms.

Digital Watermarking Program with DWT-SVD and Chaotic Encryption

MATLAB digital watermarking implementation using Discrete Wavelet Transform (DWT) method with four sub-band decomposition, focusing on LL sub-band selection. Combines Singular Value Decomposition (SVD) algorithm with DWT and employs chaotic encryption for security. Includes both GUI version (dwt_svd_GUI.rar) and M-file version for flexible implementation.
