An embedded signal detection process determines a transformation of a media
signal subsequent to the encoding of an embedded code signal into the
media signal. The process performs a logarithmic sampling of the media
signal to create a sampled signal in which scaling of the media signal is
converted to translation in the sampled signal. It then computes the
translation of the embedded code signal in the sampled signal to determine
scaling of the media signal subsequent to the encoding of the embedded
signal in the media signal.
