opencv：形态学操作-腐蚀与膨胀

#include <opencv2/opencv.hpp>

#include <iostream>

using namespace cv;

using namespace std;

int main(int argc, char** argv)

{

    Mat src = imread("f:/images/shuang001.jpg");

    Mat gray, binary;

    cvtColor(src, gray, COLOR_BGR2GRAY);

    threshold(gray, binary, 0, 255, THRESH_BINARY | THRESH_OTSU);

    imshow("src", src);

    imshow("binary", binary);

    Mat dst1, dst2;

    Mat kernel = getStructuringElement(MORPH_RECT, Size(3, 3), Point(-1, -1));

    // 腐蚀

    //erode(binary, binary, kernel);

    // 可以传入彩色图像

    erode(src, dst1, kernel);

    // 膨胀

    dilate(src, dst2, kernel);

    imshow("erode", dst1);

    imshow("dilate", dst2);

    waitKey(0);

    destroyAllWindows();

    return 0;
