代码说明:

说明:  关于半色调编码计算全息图的信息隐藏Matlab程序的说明: 算法实现主程序为CGHwatermark; 位相恢复函数为phaseSL; 用计算全息记录已知振幅和位相的复波前函数为Hologen; 半色调编码函数为AMhalftone; 嵌入信息的提取直接调用Matlab自带的FFT2函数; 主程序的函数调用关系如下 读入宿主信息和水印信息-----------phaseSL--->Hologen--->AMhalftone(完成嵌入)--->FFT2(提取水印信息) 主程序结果保存于holo&mark文件夹 对算法鲁棒性测试的程序: 1. 对于剪切操作 Cliptest 结果存放于cliptest文件夹 2. 对于缩放操作 zoomtest 结果存放于zoomtest文件夹 3. 对于旋转操作 rotatetest 结果存放于rotate文件夹 4. 对于滤波操作 filtertest 结果存放于filtertest文件夹 5. 测试算法的时间效率 timetest 6. 分析嵌入信息后图像质量与参数alpha,tao的关系 msetest(err)
