摘要：

In order to protect the copyright of JPEG2000 images, a robust watermark algorithm for JPEG2000 images is proposed. In this algorithm, watermark information is embedded by modifying the wavelet coefficients in pairs after quantization of the original image. On the precondition of robustness, the change is little by especially dealing with wavelet coefficients. Experiment results show that the algorithm has the character of transparency and is robust to common image processing operations such as compressing transition, adding noise, sharping and cutting.
