Abstract

Since there is an issue about none of robust digital watermarking uses the same robustness criteria, and consequently causes a non-practical comparison as well as slow down progress in this area. Generally, the schemes in spatial domain are usually less robust to attacks; while the schemes in frequency/transform domain are more robust to kinds of distortions. Synchronization errors can lead to significant performance loss of known image watermarking methods, which can be evidenced by the spurious effects that suite of signal processing or transfomation attacks contained in the benchmark software stirmark. Thus, in order to provide a fair benchmark for image watermarking systems, a comparison technique using the most fundamental robust frequency domain schemes (DCT, DWT and FFT) are presented in this project.
