那么你根据改正后的结果重新修改一下你给出的代码

当然可以,以下是修改后的代码:
```cpp
#include <opencv2/opencv.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main() {
Mat img = imread("circles.jpg", IMREAD_GRAYSCALE);
if (img.empty()) {
cout << "Could not read the image" << endl;
return 1;
}
// 高斯滤波
Mat img_blur;
GaussianBlur(img, img_blur, Size(3, 3), 0);
// 图像二值化
Mat img_thresh;
threshold(img_blur, img_thresh, 200, 255, THRESH_BINARY);
// Hough圆变换
vector<Vec3f> circles;
HoughCircles(img_thresh, circles, HOUGH_GRADIENT, 1, img.rows / 8, 200, 100, 0, 0);
// 绘制圆
Mat img_circles = img.clone();
for (const auto& circle : circles) {
Point center(cvRound(circle[0]), cvRound(circle[1]));
int radius = cvRound(circle[2]);
circle(img_circles, center, radius, Scalar(0, 0, 255), 2, LINE_AA);
}
// 显示图像
imshow("Original Image", img);
imshow("Blurred Image", img_blur);
imshow("Thresholded Image", img_thresh);
imshow("Circles Detected", img_circles);
waitKey();
return 0;
}
```
这个版本的代码不再访问circle[3],而是只访问circle[0]、circle[1]和circle[2],这样就能正确地执行了。
