| Abstract: | Aim A novel approach to image hiding algorithm of harmonic amalgamation is given.Methods Based on wavelet transform of watermark image and host image,low-frequency ingredient of watermark is embedded in low-frequency part of host image.Results The algorithm is given. The experimental results show that the advantage of it is of high efficiency in resisting the current various attack and data hiding , and that recovering image is good .Conclusion This technique is reasonable and satisfactory. |
