Opis

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
