c++ opencv 腐蚀膨胀

以下是C++与OpenCV实现二值形态学和灰度形态学的腐蚀膨胀处理的方法：

1. 二值形态学的腐蚀处理

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

int main()
{
    Mat src = imread("binary_image.png", IMREAD_GRAYSCALE);
    Mat dst;
    Mat kernel = getStructuringElement(MORPH_RECT, Size(3, 3));
    erode(src, dst, kernel);
    imshow("Eroded Image", dst);
    waitKey(0);
    return 0;
}

2. 二值形态学的膨胀处理

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

int main()
{
    Mat src = imread("binary_image.png", IMREAD_GRAYSCALE);
    Mat dst;
    Mat kernel = getStructuringElement(MORPH_RECT, Size(3, 3));
    dilate(src, dst, kernel);
    imshow("Dilated Image", dst);
    waitKey(0);
    return 0;
}

3. 灰度形态学的腐蚀处理

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

int main()
{
    Mat src = imread("gray_image.png", IMREAD_GRAYSCALE);
    Mat dst;
    Mat kernel = getStructuringElement(MORPH_RECT, Size(3, 3));
    erode(src, dst, kernel);
    imshow("Eroded Image", dst);
    waitKey(0);
    return 0;
}

4. 灰度形态学的膨胀处理

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

int main()
{
    Mat src = imread("gray_image.png", IMREAD_GRAYSCALE);
    Mat dst;
    Mat kernel = getStructuringElement(MORPH_RECT, Size(3, 3));
    dilate(src, dst, kernel);
    imshow("Dilated Image", dst);
    waitKey(0);
    return 0;
}
