Abstract
In this paper, we will provide an overview of the wavelet-based
watermarking
techniques available today. We will see how previously proposed methods
such as spread-spectrum watermarking have been applied to the wavelet
transform domain in a variety of ways and how new concepts such as
the multi-resolution property of the wavelet image decomposition can
be exploited.
One of the main advantages of watermarking in the wavelet domain is
its compatibility with the upcoming image coding standard, JPEG2000.
Although many wavelet-domain watermarking techniques have been proposed,
only few fit the independent block coding approach of JPEG2000. We
will illustrate how different watermarking techniques relate to image
compression and examine the robustness of selected watermarking algorithms
against image compression.
