rects.push_back(mr);这句话是什么意思？

Question

vector<vector<Point> >::iterator itc= contours.begin();vector<RotatedRect> rects;//Remove patch that are no inside limits of aspect ratio and area.  while (itc!=contours.end()) {//Create bounding rect of objectRotatedRect mr= minAreaRect(Mat(*itc));if( !verifySizes(mr)){itc= contours.erase(itc);}else{++itc;rects.push_back(mr);}}

Answer 1

vector<RotatedRect> rects;
它是一个vector对象啊，调用vector对象的push_back方法。
