In this paper, we propose a binary value based progressive image watermarking approach for digital right protection. The proposed method embed most watermark information into region of interest(ROI) of an image. Therefore, a client on Internet can decode the watermark while receiving the image, moreover, most watermark information would be decoded while the ROI of the image is received. In order to...
In this paper, we propose a binary value based progressive image watermarking approach for digital right protection. First, a new binary valued watermarking method for wavelet domain images are introduced, and then a progressive watermark detecting scheme for Internet environment is introduced. Its performance was evaluated with two types of experiments (1) robustness against image attacks and (2)...
Wavelet packet transform can be viewed as a generalization of the discrete wavelet transform and a best wavelet basis in the sense of some cost metric can be found within a large library of permissible bases. In this paper, we proposed a genetic watermarking scheme based on the wavelet packet transform. Genetic algorithm is used to select an appropriate basis from permissible bases of wavelet packet...
