A Robust Image Watermarking Algorithm against JPEG2000

In this paper, a robust meaningful image watermarking algorithm against JPEG2000 standard which will be the most popular compression technique is proposed. The meaningful watermarking algorithm is based on discrete wavelet transform and linear interpolation. In order to improve the robustness of the algorithm, we select the important horizontally and vertically lowpass coefficients as the embedding points. Experiments showed that the algorithm had not only good information capacity but also good security, invisibility and undetectability. Furthermore, the robust algorithm can stand against JPEG2000 and JPEG lossy compression effectively, and realize watermark blind detecting.
