A robust image watermarking scheme using multiwavelet tree

In this paper, we attempt to develop image watermarking algorithms which are portable to a variety of applications such as copyright protection, fingerprinting and identification. Therefore, we require that the watermark be binary and be not only detectable but also extractable. The embedding technique is based on the parent-child structure of the muldwavelet transform called "triple tree" and this technique does not require the original image in the watermark extraction. The experimental results show that the watermark survives to most of the attacks which were included in this study.
