摘　　要：目的　给出一种图像融合隐藏算法。方法　通过对宿主图像和水印图像的小波变换,该算法把水印图像的低频成分嵌入到原始宿主图像的低频部分。结果　给出了该算法,通过实验得出其抗攻击能力和隐藏能力强,提取的水印图像质量良好。结论　仿真结果证明该算法是有效的和可行的。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.
