测试程序：

 #include <opencv2/opencv.hpp>
 #include <iostream>
 using namespace cv;

 int main(int argc, char** argv)
 {
     Mat srcImage = imread("test.jpg");

     imshow("[My Picture]", srcImage);

     waitKey();

 }

膨胀和腐蚀：

 #include <opencv2/opencv.hpp>
 #include <iostream>
 //#include <opencv2/highgui/highgui.hpp>
 //#include <imgproc/imgproc.hpp>
 using namespace cv;

 int main(int argc, char** argv)
 {
     Mat srcImage = imread("test.jpg");
     imshow("[原图]", srcImage);

     //进行膨胀操作
     Mat element1 = getStructuringElement(MORPH_RECT, Size(, ));
     Mat dstImage1;
     dilate(srcImage, dstImage1, element1);
     imshow("[膨胀效果图]", dstImage1);

     //进行腐蚀操作
     Mat element2 = getStructuringElement(MORPH_RECT, Size(, ));
     Mat dstImage2;
     erode(srcImage, dstImage2, element2);
     imshow("[腐蚀效果图]", dstImage2);

     waitKey();

     return ;
 }

图像模糊：

 #include <opencv2/opencv.hpp>
 #include <iostream>
 //#include <opencv2/highgui/highgui.hpp>
 //#include <imgproc/imgproc.hpp>
 using namespace cv;

 int main(int argc, char** argv)
 {
     Mat srcImage = imread("test.jpg");
     imshow("[原图]", srcImage);

     //进行均值滤波操作
     Mat dstImage1;
     blur(srcImage, dstImage1, Size(,));
     imshow("[效果图]", dstImage1);

     waitKey();

     return ;
 }

Canny边缘检测：

 #include <opencv2/opencv.hpp>
 #include <iostream>
 //#include <opencv2/highgui/highgui.hpp>
 //#include <imgproc/imgproc.hpp>
 using namespace cv;

 //Canny边缘检测
 int main(int argc, char** argv)
 {
     Mat srcImage = imread("test.jpg");
     imshow("[原图]", srcImage);

     Mat edge, gray;
     //将原图转换成灰度图像
     cvtColor(srcImage, gray, COLOR_BGR2GRAY);
     //均值滤波降噪
     blur(gray, edge, Size(, ));
     //运行Canny算子
     Canny(edge, edge, , , );

     imshow("[效果图]", edge);

     waitKey();

     return ;
 }
