I am working on face detection using openCv in iOS platform. I am using openCv in c++. It detects face nicely and I am able to draw a rectangle around this face. But I need to show a overlay image instead of rectangle. Here is my code.
- (void)processImage:(Mat&)image;
{
cv::cvtColor(image, img, CV_BGR2GRAY);
equalizeHist(img, img);
NSString* cascadePath = [[NSBundle mainBundle]
pathForResource:@"haarcascade_frontalface_alt2"
ofType:@"xml"];
CascadeClassifier face_cascade;
face_cascade.load([cascadePath UTF8String]);
std::vector<cv::Rect> faces;
face_cascade.detectMultiScale(img, faces, 1.1,
2, haarOptions, cv::Size(30, 30));
for(unsigned int i = 0; i < faces.size(); i++) {
cv::Point p1(faces[i].x + faces[i].width, faces[i].y + faces[i].height);
cv::Point p2(faces[i].x , faces[i].y);
cv::Scalar magenta = cv::Scalar(255, 10, 255);
cv::Point center( faces[i].x + faces[i].width*0.5, faces[i].y + faces[i].height*0.5 );
//const std::string text = Eye;
cv::putText(image, Face,p2 ,FONT_HERSHEY_SIMPLEX, 1, Scalar(0,200,200), 2);
cv::rectangle(image, p1, p2, magenta,1,8,0);
}
}
Here is my output..
Now I want replace this rectangle with an overlay image. Is it possible? If so then please help me. Thanks in advanced.
