Paper Abstract

In recent years it has been recognized that embedding information in wavelet transform domain leads to more robust watermarks. In particular, several approaches have been proposed to address the problem of watermark embedding combined to wavelet based image coding. In this paper, we present an alternative to quantization based blind watermarking strategy in the framework of JPEG2000 still image compression. The central contribution is the proposal of modified Quantization Index Modulation watermark design to reduce fidelity problem. We also show that the proposed watermarking scheme exhibits a high robustness with respect to JPEG2000 compression and Gaussian noise attacks. After detailing the proposed solution, system performance on image quality as well as robustness will be evaluated.
