Kernel的构造与高斯核的构造

通过阅读资料Mat构造初始化来构造Kernel。

通过实验我选用了两种方式，资料中的5（2）、7并稍加修正。

/// Kernel构造一Mat Kernel = (Mat_<double>(3,3)<<1/9.0,1/9.0,1/9.0,1/9.0,1/9.0,1/9.0,1/9.0,1/9.0,1/9.0);/// Kernel构造二double m[3][3] = {{1/9.0,1/9.0,1/9.0},{1/9.0,1/9.0,1/9.0},{1/9.0,1/9.0,1/9.0}};Mat Kernel = Mat(3, 3, CV_64FC1, m);

另外根据书本所提出的高斯核的构造方法构造了简单高斯核。

/// 产生高斯核《数字图像处理与机器处理》P152，式5-7Mat GaussinaKenel;GaussinaKenel.create(3 , 3, CV_64FC1);double sigma = 0.8;//3*3模板选择0.8，更大的模板可适当增加sigmafor (int i = 0; i < 3; ++i){for (int j = 0; j < 3; ++j){GaussinaKenel.at<double>(i,j) = exp(-(i*i + j*j)/2/sigma/sigma)/(2*CV_PI*sigma*sigma);}}/// 输出该高斯核for (int i = 0; i < 3; ++i){for (int j = 0; j < 3; ++j){double a = GaussinaKenel.at<double>(i,j);if((j+1)%3)cout << a <<" ";else cout << a << endl;}}
