Geometrically invariant image watermarking based on fast Radial Harmonic Fourier Moments

作者：

Highlights：

• A fast and precise computing method for Radial Harmonic Fourier Moments (RHFMs) is proposed.

• The proposed method has improved the reconstruction performance and reduced the time complexity significantly.

• The relationship between reconstruction performance and the number of used RHFMs in the reconstruction process is discussed.

• Come up with a new robust image watermarking algorithm by using the proposed method for RHFMs.

• The results show the proposed watermarking algorithm has an outstanding watermark invisibility and robustness.
