RISA Robust Digital Blind Image Watermarking Based on Spread Spectrum in DCT Domain
This paper presents a new method in blind digital watermarking based on discrete cosine transform (DCT)....
Optimal DWT-SVD Domain Image Watermarking Using Multi-Objective
In this paper, we present an optimal Discrete Wavelet
Transform-Singular Value Decomposition (DWT-SVD)
based image watermarking scheme using Pareto-based
Multi-Objective Evolutionary Algorithm (MOEA). After...
A new adjustable blind Watermarking based on GA and SVD
watermarking- is one of the methods to protect owner rights. Two main concepts in watermarking are imperceptibility and robustness of the watermark. A tradeoff between these two features exists, which can be introduced as an optimization problem. Genetic...
Robust adaptive observer for fractional order nonlinear systems: An LMI approach
Two level DCT Based Digital Watermarking
In this paper, we propose a DCT-based blind
watermarking scheme based on spread spectrum
communications. We compute the DCT of non overlapping
8x8 blocks of the host image. Then using the DC coefficients
of each block we...
Fast Watermarking Based on QR Decomposition in Wavelet Domain
A novel blind watermarking technique based on QR decomposition in still images is proposed. The method is implemented in wavelet domain and its robustness has been evaluated against some image processing attacks and the results have been compared...
