Abstract :
In this paper four typical watermarking techniques are compared and tested extensively, which not only include the private system, the semi-private system but also the public schemes. The comparisons mainly focus on the evaluation of robustness and visual image quality. The benchmarking is the popular Stirmark 3.1. Results show that the chosen schemes do not have the same behavior and no method has all the desirable characteristics.
