openCV C++ 形态学应用 对图片进行细化，粗化和提取骨架的具体代码

对于你的第一个问题，以下是形态学应用的代码示例：

1. 细化

Mat src = imread("image.jpg", IMREAD_GRAYSCALE);
Mat dst;
threshold(src, dst, 128, 255, THRESH_BINARY);
Mat element = getStructuringElement(MORPH_CROSS, Size(3, 3));
Mat skel(src.size(), CV_8UC1, Scalar(0));
Mat temp;
Mat eroded;
do {
    erode(dst, eroded, element);
    dilate(eroded, temp, element);
    subtract(dst, temp, temp);
    bitwise_or(skel, temp, skel);
    eroded.copyTo(dst);
} while (countNonZero(dst) != 0);

2. 粗化

Mat src = imread("image.jpg", IMREAD_GRAYSCALE);
Mat dst;
threshold(src, dst, 128, 255, THRESH_BINARY);
Mat element = getStructuringElement(MORPH_CROSS, Size(3, 3));
Mat temp;
erode(dst, temp, element);
dilate(temp, dst, element);

3. 提取骨架

Mat src = imread("image.jpg", IMREAD_GRAYSCALE);
Mat dst;
threshold(src, dst, 128, 255, THRESH_BINARY);
Mat element = getStructuringElement(MORPH_CROSS, Size(3, 3));
Mat skel(src.size(), CV_8UC1, Scalar(0));
Mat temp;
do {
    erode(dst, temp, element);
    dilate(temp, temp, element);
    subtract(dst, temp, temp);
    bitwise_or(skel, temp, skel);
    temp.copyTo(dst);
} while (countNonZero(dst) != 0);
