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)

This paper presents a new classification algorithm using
colour and texture for obstacle detection. Colour information is
computationally cheap to learn and process. However in many cases,
colour alone does not provide enough information for classification.
Texture information can improve classification performance but usually
comes at an expensive cost.
