opencv：形态学操作-开闭操作

#include <opencv2/opencv.hpp>

#include <iostream>

using namespace cv;

using namespace std;

int main(int argc, char** argv)

{

    Mat src = imread("f:/images/qq/kaibi.png");

    Mat gray, binary;

    cvtColor(src, gray, COLOR_BGR2GRAY);

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

    imshow("src", src);

    imshow("binary", binary);

    Mat dst;

    Mat kernel = getStructuringElement(MORPH_RECT, Size(4, 4), Point(-1, -1));

    // 这样可以提取水平的线

    //Mat kernel = getStructuringElement(MORPH_RECT, Size(15, 1), Point(-1, -1));

    morphologyEx(src, dst, MORPH_OPEN, kernel, Point(-1, -1), 1);

    //morphologyEx(src, dst, MORPH_CLOSE, kernel, Point(-1, -1), 1);

    imshow("morphologyEx", dst);

    waitKey(0);

    destroyAllWindows();

    return 0;
