Abstract
In this paper objective is to develop a robust image watermarking method in contourlet domain using GA(Genetic Algorithm) to improve the quality and robustness of the watermarked image, by reducing the (BER)Bit Error Rate to with stand against common image processing attacks. Selecting more Co-efficient in more directions is achieved by means of combining Laplacian Pyramid with Directional filter bank structure which captures directional information efficiently.

Summary
In this paper objective is to develop a robust image watermarking method in contourlet domain using GA(Genetic Algorithm) to improve the quality and robustness of the watermarked image, by reducing the (BER)Bit Error Rate to with stand against common image processing attacks. Igital Watermarking is the process of possibly irreversibly embedding information into a digital signal. The signal may be audio, video, or pictures for example. If the signal is copied the information is carried in the copy. The information is visible in the picture or video. The information is text or a logo which identifies the owner of the media. The image on the right has a visible watermark. When a television broadcaster adds its logo to the corner of transmitted video, this is a visible watermark
