直接序列扩频水印的嵌入与提取
说明: 实现直接序列扩频水印的嵌入与提取。基于待嵌入消息生成二进制水印序列,生成扩频码,用消息序列调制生成水印序列。依次处理灰度图像的每一个载体图像像素,根据相应位置 水印序列完成嵌入修改。(Realize the embedding and extraction of direct sequence spread spectrum watermark. The binary watermark sequence is generated based on the message to be embedded, the spread spectrum code is generated, and the watermark sequence is generated by message sequence modulation. Each carrier image pixel of gray image is processed in turn, and the embedding modification is completed according to the corresponding position watermark sequence.)

曲面拟合法是一种高精度、计算量小、抗噪性能强的方法,当前已被广泛地应用于
各种场景。比如岩石材料的变形测量、电子器件变形的测量、基于掌纹图像相关匹
配的重复定位技术等。曲面拟合法能够成功计算出亚像素位移的前提是整像素搜索阶
段可以正确搜索出模板的整像素匹配点,一旦整像素匹配点搜索出现错误,那么亚像素
测量阶段所得到的位移距离就会失去意义。
使用不同的拟合函数对相关系数矩阵进行曲面拟合,会对结果产生一定的影响,比
较常用的拟合函数有二次函数、三次函数、高斯函数等。(Surface fitting method is a high-precision, computational complexity is small, strong anti-noise performance method, has been widely used in various scenes. For example, deformation measurement of rock materials, deformation measurement of electronic devices, and repetitive location technology based on palmprint image correlation matching. Surface fitting method can successfully calculate the sub-pixel displacement on the premise that the whole pixel search stage can correctly search the template of the whole pixel matching point, once the whole pixel matching point search error, then the sub-pixel measurement phase of the displacement distance will be meaningless.
Using different fitting functions to fit the surface of the correlation coefficient matrix will have a certain impact on the results. The commonly used fitting functions are quadratic function, cubic function, Gaussian function and so on.)
