我尝试编写一种方法,将二进制图像中的对象缩小为它们的质心(即质心)。
答案 0 :(得分:-1)
Mat *pMA_Out, Mat *pMA_In, int mode, int method, unsigned int thickness
//Allocate contours
vector<vector<Point>> vvp_countours;
//Find countours
findContours(
*pMA_In,
vvp_countours,
mode,
method,
Point(0, 0));
//Get the moments
vector<Moments> v_moments(vvp_countours.size());
for(int c = 0; c < vvp_countours.size(); c++)
v_moments[c] = moments(vvp_countours[c], false);
//Get the mass centers
vector<Point2f> v_centroid(vvp_countours.size());
for(int c = 0; c < vvp_countours.size(); c++)
v_centroid[c] = Point2f(
v_moments[c].m10 / v_moments[c].m00,
v_moments[c].m01 / v_moments[c].m00);
//Create output image
Mat MA_tmp = Mat(pMA_In->size(), CV_8UC1, Scalar(0));
//Draw centroids
for(int c = 0; c < v_centroid.size(); c++)
line(
MA_tmp,
v_centroid[c],
v_centroid[c],
Scalar(255),
thickness,
8);
*pMA_Out = MA_tmp.clone();
