STIRMARK
This page mirrors information from the Official Stirmark Page, provided by Fabien Petitcolas.
Introduction
Stirmark is a benchmarking tool for digital watermarking
technologies. Given a watermarked inpute image, Stirmark generates a
number of modified images which can then be used to verify if the
embedded watermark can still be detected. Stirmark also proposes a
procedure to combine the different detection results and compute an
overall score ranging between 0 and 1.
Stirmark has been developed by Fabien Petitcolas during his Pd.D. at
Cambridge University, UK. Since its first publication in 1997,
Stirmark has gained large interest from the watermarking community and
it is currently the most widely used benchmarking suite for digital
watermarking technologies.
