Genetic Watermarking Based on Wavelet Packet Transform

摘要：

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 transform to increase the robustness of the embedded watermarks. Experimental results show that the proposed method can increase the capability to resist some image processing methods if an appropriate .tness function of GA was adopted.
