Watermarking Algorithm based using Genetic Algorithm and HVS

In this work, a watermarking algorithm is proposed using Genetic algorithm and discrete wavelet transformation. The algorithm proposed is to improve both robustness and fidelity of the watermarked image. Fuzzy Inference system is used to determine the embedding strength based on HVS properties of the image. To test the robustness different attacks are performed and the NC (Normalized cross correlation) is computed. The algorithms showed better results and good quality for watermarked image.
