hello i am new to cpp and need help. Tell me, there is such a code (working), how can I take pictures of the recognized face?
#include <opencv2/opencv.hpp>
#include <opencv2/face.hpp>
#include <opencv2/imgcodecs.hpp>
#include “drawLandmarks.hpp”
using namespace std;
using namespace cv;
using namespace cv::face;
int main(int argc,char** argv)
{
// Load Face Detector
CascadeClassifier faceDetector(“haarcascade_frontalface_alt2.xml”);
// Create an instance of Facemark
Ptr<Facemark> facemark = FacemarkLBF::create();
// Load landmark detector
facemark->loadModel("bfmodel.yaml");
// Set up webcam for video capture
VideoCapture cam("myvideo.mp4");
// Variable to store a video frame and its grayscale
Mat frame, gray;
// Read a frame
while(cam.read(frame))
{
// Find face
vector<Rect> faces;
// Convert frame to grayscale because
// faceDetector requires grayscale image.
cvtColor(frame, gray, COLOR_BGR2GRAY);
// Detect faces
faceDetector.detectMultiScale(gray, faces);
// Variable for landmarks.
// Landmarks for one face is a vector of points
// There can be more than one face in the image. Hence, we
// use a vector of vector of points.
vector< vector<Point2f> > landmarks;
// Run landmark detector
bool success = facemark->fit(frame,faces,landmarks);
if(success)
{
// If successful, render the landmarks on the face
for(int i = 0; i < landmarks.size(); i++)
{
drawLandmarks(frame, landmarks[i]);
}
}
// Display results
imshow("Facial Landmark Detection", frame);
// Exit loop if ESC is pressed
if (waitKey(1) == 27) break;
}
return 0;
}
