| Abstract: | The enlargement use of multimedia content through
online services in addition to the widespread of new
image technologies and data exchanges has created the
need for new techniques able to insure copyright
protection and data owner identification. Considering
the deficiencies of steganographie and cryptography,
watermarking is nowadays a new technique that
provides an efficient mean for resolving these problems.
Watermark embedding techniques depend on the
representation domain of the image (spatial, frequency,
and multi-resolution). Every domain has its specific
advantages and limitations. Moreover, each technique in
a chosen domain is found to be robust to specific sets of
attack types. The ultimate goal of each technique is to
allow the embedded watermark to be invisible and
robust against a wide range of attacks. The most
damaging unintentional attacks are compression
techniques. Many of these last techniques are based on
the new coding procedures using Multi-resolution
domain. In order to develop a watermarking technique
robust against large sets of attacks, we must exploit this
domain to overcome these attacks constraints. In this
paper, a study is developed considering all the
parameters contributing in the watermarking scheme.
An optimal point allowing robustness and
imperceptibility of the embedded watermark is
established. Using these optimized parameters any
technique based on the multi-resolution domain can
reach the maximum of imperceptibility and robustness
