Utilization of Watermarking Techniques for Securing Digital Images

Digital multimedia is easily duplicated and distributed using many free softwares. It is important to have copyright protection to save owners copyrights. There are many protection techniques; one of them is watermarking. In watermarking techniques the objective is to embed a watermark label or image into the original images audios or videos. This book presents two robust image watermarking techniques; homomorphic Singular Value Decomposition (SVD) watermarking in Discrete Wavelet Transform (DWT) domain and 3-level Discrete Stationary Wavelet Transform (DSWT) in the Discrete Cosine Transform (DCT) domain. A study for watermarking on different color coordinate systems is included in this book with results
