Robust Image Watermarking Technique Based on Genetic Algorithm Optimization and Even Odd Modulation

Robustness is one of the important issues in watermarking. In particular, robustness against JPEG compression is especially actual. Nowadays there are many different applications requiring image compression, such as Internet, satellite imaging, remote sensing, multimedia, preservation of art work and so on. In this paper, an effective watermarking technique based on the genetic algorithm optimization and even-odd modulation in frequency domain is presented. The genetic algorithm finds the optimum watermark strength and location for its embedding in a spectrum of the cover image. Experimental results have demonstrated high values of robustness and fidelity of the proposed scheme.
