CGHwatermarkmatlabcode
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)
