- This paper exploits the characteristics of both wavelet packet transform and singular values decomposition to propose a high capacity and robust watermarking technique. From the wavelet packets, the best wavelet sub-band, in the sense of evaluation metric, is found by using the particle swarm optimization algorithm to meet the requirements of imperceptibility and robustness of the watermarking algorithm. After the operation of particle swarm optimization, the watermark image can be embedded into the cover image, and the watermarked image is obtained. Intentional signal processing or malicious attacks are expected, and the watermarking algorithm is considered to keep the integrity for the media file. Experimental results demonstrate that the proposed method can increase the capability to resist such attacks. Moreover, the watermarked image quality can be guaranteed based on the inherent characteristics of the singular values decomposition concept.
