Dual Chaotic Systems and SVM Based Robust Digital Watermarking Algorithm
Jianjun Hou · Journal of Beijing Jiaotong University · 2008
There are many applications of support vector machine (SVM) in signal field for its better classifying and regression performance. A new robust digital watermarking algorithm was presented in this paper. Firstly, host image was divided by the same size blocks, and training blocks and embedded blocks were selected by Arnold transform.Then the watermark sequences modulated by Logistic system were embedded by modifying the center pixel value in the embedded blocks. The simulation results show that the proposed algorithm not only has the high security and good visual quality, but also can resist many attacks.
