This is the c++ code.
vector<Moments> mu(contours.size() );
for( int i = 0; i < contours.size(); i++ ){
mu[i] = moments( contours[i], false );
}
//Mass center
vector<Point2f> mc( contours.size() );
for( int i = 0; i < contours.size(); i++ ){
mc[i] = Point2f( mu[i].m10/mu[i].m00 , mu[i].m01/mu[i].m00 );
}
This is my code so far in android. I can't convert the mass center to android.
//moments
List<Moments> mu = new ArrayList<Moments>(contours.size());
for (int i = 0; i < contours.size(); i++) {
mu.add(i, Imgproc.moments(contours.get(i), false));
}
//mass center
List<MatOfPoint2f> mc = new ArrayList<MatOfPoint2f>(contours.size());
for( int i = 0; i < contours.size(); i++ ){
mc.add((mu.get(i).get_m10() / mu.get(i).get_m00() , mu.get(i).get_m01()/mu.get(i).get_m00()));
}
Error in this line :
mc.add((mu.get(i).get_m10() / mu.get(i).get_m00() , mu.get(i).get_m01()/mu.get(i).get_m00()));
Thanks in advance.
This code will find the position of all contours.
List<Moments> mu = new ArrayList<Moments>(Contours.size());
for (int i = 0; i < Contours.size(); i++) {
mu.add(i, Imgproc.moments(Contours.get(i), false));
Moments p = mu.get(i);
int x = (int) (p.get_m10() / p.get_m00());
int y = (int) (p.get_m01() / p.get_m00());
Core.circle(rgbaImage, new Point(x, y), 4, new Scalar(255,49,0,255));
}
