Abstract

Abstract: In this paper，a watermarking algorithm based on digital holography and block energy analysis of the wavelet transform parameters is proposed.The Fourier CGH is created after expending the space size of the original image with zero.So it eliminates the problem of aliasing image after reproduction.Then the original host image will be decomposed by wavelet transform and the hologram will be embedded in the wavelet parameters whose block energy is larger than others.The experiment proves that the algorithm has very good invisible property and robust property.

Key words: digital watermark, digital holography, wavelet transform, block energy

摘要： 提出了一种基于数字全息和小波系数块能量分析的水印算法。待隐藏的水印图像通过在空域零扩展后再生成其傅里叶全息图，从而消除了再现后孪生像的混叠问题，然后将原宿主图像进行小波分解，把全息图嵌入在分块能量较大的小波系数中。仿真实验证明算法具有较好的透明性和鲁棒性。
