Abstract :
Image watermarking with both insensible detection and high robustness capabilities is still a challenging problem for copyright protection up to now. Transformed domain has been found more suitable to hide the watermark data. For watermark embedding, transformed domain based watermarking schemes are quite robust against those attacks which anyhow do not have large impact on perceptual quality like JPEG compression. This paper explores an opportunity to improve the robustness of transformed domain based watermarking schemes by preprocessing the image. This attempt is to find whether we can make our images strong enough against such attacks in advance. We are considering histogram equalization attack that has impact on perceptual quality.
