通过MATLAB软件对全息水印的Vander Lugt相关检测进行了仿真，结果表明光学相关检测能够提取出载体图像中的原始水印信息，原始水印和其共轭像位置输出相关峰不受提取图像对比度的影响。对含全息数字水印图像进行了嵌入强度、位压缩、剪切、嵌入白噪声的相关实验，结果表明：相关峰均大于3，能够提取出原始水印相关峰信息，可以用于版权保护；同时验证了全息水印具有较强的抗低通滤波、噪声、剪切性能，具有较好的鲁棒性。

The Vander Lugt correlation detection of holographic watermark was simulated by MATLAB software. The original watermark information was obtained from the carrier image by correlation detection. The correlation peak was also obtained and appeared in the position of the original watermark image and the conjugated image without effect by the contrast gradient of the extraction image. The optical correlation detection was set up and used to detect the original watermark information. The correlation peak was obtained from the carrier images distorted by noise added, JPEG compression, part occluded, and low pass filter. The results showed that the correlation peak is bigger than 3; holographic watermark can extract correlation peak of original watermarked image and can be used in copyright protection. It was proved that holographic watermark has strong resistance to low pass filter, noise, and cutting; it has good robustness.
