Question

我正在尝试分别在所有颜色通道中检测图像中的圆心。我的代码看起来像这样：

#include "opencv/cv.h"
#include "opencv/highgui.h"
#include "opencv2/opencv.hpp"
#include <opencv2/highgui/highgui.hpp>
#include "opencv2/imgcodecs.hpp"
#include <opencv2/imgproc/imgproc.hpp>
#include <stdlib.h>
#include <stdio.h>

#include <iostream>
#include "opencv2/core.hpp"
//#include "features2d.hpp"

using namespace cv;
using namespace std;

vector<KeyPoint> keypoints;

Mat imageSource;

Mat colorChannels[3];

int main(int argc, char* argv[])
{
    SimpleBlobDetector::Params params;
    params.minDistBetweenBlobs = 50;
    params.filterByArea = true;
    params.minArea = 50000;

    params.filterByColor = true;
    params.blobColor = 255;

    Ptr<SimpleBlobDetector> detector = SimpleBlobDetector::create();
    imageSource = imread("opencv-logo.jpg", CV_LOAD_IMAGE_COLOR);

    split(imageSource, colorChannels);

    threshold(colorChannels[1], colorChannels[1], 100, 255, THRESH_BINARY);
    bitwise_not(colorChannels[1], colorChannels[1]);
    detector->detect(colorChannels[1], keypoints);

    int number = keypoints.size();

    printf("%d\n", number);

    namedWindow("Original", WINDOW_AUTOSIZE);
    imshow("Original", colorChannels[1]);

    cvWaitKey(0);
    return 0;
}

但每次我尝试运行它时，输出不同的矢量大小，如-592369722或1062631863 - 没什么正常的。尝试使用blobdetector的参数，但结果是一样的。如果我尝试取消注释#include "features2d.hpp"，整个程序就会崩溃。我的OpenCV版本是3.4.1。我该如何解决这个问题？
