Hui Chen, Fei LONG, Fei Long · DEStech Transactions on Computer Science and Engineering · 2019
In order to improve the performance of digital watermarking system, a novel watermarking algorithm for blind watermarking based on the least significant bits and support vector machine. Firstly, digital watermarking was pretreated by binaryzation. Subsequently, the watermark signal is embedded into least significant bit of the low frequency coefficients by the Discrete Wavelet Transformation. Finally, the trained support vector machine is used to extract the attacking vetors. Simulation results show that the watermarking algorithm has good invisibility and robustness to general attacks and geometrical distortions.
