A robust image watermarking algorithm based on stationary multiwavelet transform

Due to the advantages of multi-wavelet transformation in image processing, this paper presents a image watermarking algorithm based on stationary multiwavelet. The simulation results show that relative to general watermarking algorithm based on scalar wavelet or multiwavelet transformation, this algorithm can not only resist noise pollution better, but also embed watermark content as much as possible without affecting the image quality, under the same conditions. The algorithm ensures the original image watermarking information is not easily detected and improves the robustness of the watermark information.
