人脸识别的一段代码，请问这个语句怎么看

#include "opencv2/core/core.hpp"

#include "opencv2/highgui/highgui.hpp"
#include "opencv2/imgproc/imgproc.hpp"

#include
#include

using namespace std;
using namespace cv;

string face_cascade_name = "haarcascade_frontalface_alt.xml";
CascadeClassifier face_cascade;
string window_name = "人脸识别";

void detectAndDisplay( Mat frame );

Answer 1

将光标定位在detectAndDisplay，然后右键，转到定义（goto declareation）
