Abstract
This paper mainly comes up with a new watermarking method based on host image analysis and genetic algorithm. Through the characteristics of human visual system, the host image analysis can ensure the imperceptibility. It greatly enhance the embedding capacity of the watermark under the same visual effect, which can embed more watermark in the host image. The genetic algorithm is used in embedding process. It can not only improve the image quality, but also enhance the security and robustness of the watermarked image in a large extent. This algorithm satisfies an optimal compromise between the robustness and image quality. Besides that, the experimental results show that this method has great influence on transparency and robustness.
