Novel Watermarking Scheme for Image Up-Sampling Based Multiple Description Coding Frames
Linlin Tang, Jeng‐Shyang Pan, Ming Zhao · International Conference on Information Security · 2011
A novel watermarking scheme is proposed for up-sampling based multiple description coding frames in this paper. Secret information is embedded in the DWT image. Sup-sampling algorithm is applied on transformed image to introduce some redundancy between different channels. Good performance of the new frame to against noise and to resist the compression attacks is shown in the experimental results.
