In recent years, many works on digital image watermarking have been proposed all aiming at protection of the copyright of an image document or authentication of data. With the help of my proposed algorithm the watermarked image contrast can be enhancement with the help of my contrast enhancement algorithm & watermark can easily be extracted in both clean and noisy environments. Experiments are performed to verify the robustness of the proposed algorithm. The results show that the proposed algorithm is superior to other algorithm in terms of providing a high PSNR. It is also shown that the proposed algorithm is highly robust against various kinds of attacks such as compression, noise, filtering, cropping & rotation.
