Digital watermarking by using a feature-based multiwavelet fusion approach

In this paper, a scheme based on a multiwavelet transform for digital image watermarking is presented. The algorithm tries to integrate the effect of compression and image feature measurement. The information of the watermark is embedded into the salient feature of the host image that will survive most kinds of distortions or attacks. The general procedure for transform domain watermarking consists of three steps: host image decomposition, watermark embedding, and reconstruction of the watermarked image. The preliminary results indicate the feasibility of the promising approach. Extensive experiments will be carried out to improve the robustness of the algorithm.
