I have been working on eye detection and I want to detect and then extract the eyes from video feed at specific interval. I want to store the detected eyes in form of images. I have done the detection of eyes using haar cascade. Now I just want to store the detected eyes in form of images. Can anyone tell me what I can do to for the problem ? The detection code is as follows
include<stdio.h>
include<math.h>
include<opencv\cv.h>
include<opencv\highgui.h>
include<opencv2\objdetect\objdetect.hpp>
include<opencv2\highgui\highgui.hpp>
include<opencv2\imgproc\imgproc.hpp>
include<vector>
using namespace std; using namespace cv;
int main() { CascadeClassifier face, eye; if(!face.load("C:\HAAR\haarcascade_frontalcatface.xml")){
printf("Error Loading Face Cascade");
return -1;
}
if(!eye.load("C:\\HAAR\\haarcascade_eye_tree_eyeglasses.xml")){
printf("Error Loading Eye Cascade");
return -1;
}
VideoCapture capture(0);
if(!capture.isOpened())
{
printf("Error opening Video Stream");
return -1;
}
Mat capimg,greyimg;
vector<Rect> faces,eyes;
while(1)
{
capture>>capimg;
waitKey(10);
cvtColor(capimg, greyimg, CV_BGR2GRAY);
cv::equalizeHist(greyimg,greyimg);
face.detectMultiScale(greyimg, faces, 1.1, 10, CV_HAAR_SCALE_IMAGE | CV_HAAR_DO_CANNY_PRUNING, cvSize(0,0), cvSize(300,300));
for(int i=0; i < faces.size(); i++)
{
Point pt1(faces[i].x+faces[i].width,faces[i].y+faces[i].height);
Point pt2(faces[i].x,faces[i].y);
Mat faceroi=greyimg(faces[i]);
eye.detectMultiScale(faceroi, eyes,1.1, 2, 0|CV_HAAR_SCALE_IMAGE, Size(30,30));
for(size_t j=0; j<eyes.size(); j++)
{
Point center(faces[i].x+eyes[j].x+eyes[j].width*0.5,faces[i].y+eyes[j].y+eyes[j].height*0.5);
int radius = cvRound((eyes[j].width+eyes[j].height)*0.25);
circle(capimg, center, radius, Scalar(255,0,0),2,8,0);
}
rectangle(capimg, pt1, pt2, cvScalar(0,255,0),2,8,0);
}
imshow("Result",capimg);
waitKey(3);
char c= waitKey(3);
if (c==27)
break;
}
return 0;
}
