Hi guys,
how to get frame rate per second in openCv live capture face detection. I have tried using capture property (VideoCapture.get(5)). but it doesnt work and give me 0 as the result. I also tried answer given in this question and i get approx 1000++ fps. i dont think this the correct fps because my live capture quite lag. by the way i am using java.
here is snipped of my code
//-- 2. Read the video stream
Mat webcam_image=new Mat();
VideoCapture capture =new VideoCapture(0);
Thread.sleep(1000);
if( capture.isOpened())
{
while( true )
{
double t = (double)Core.getTickCount();
capture.read(webcam_image);
if( !webcam_image.empty() )
{
frame.setSize(webcam_image.width()+40,webcam_image.height()+60);
//-- 3. Apply the classifier to the captured image
webcam_image=faceDetect.detect(webcam_image);
//-- 4. Display the image
framePanel.MatToBufferedImage(webcam_image);
framePanel.repaint();
}
else
{
System.out.println(" Image is empty. Break!");
break;
}
t = ((double)Core.getTickCount() - t) / Core.getTickFrequency();
System.out.println("FPS "+ 1000.0/t);
}
}
return;
}
I also tried technique from this blog, but i get 0.00 fps.
Any suggestion or what technique i should use to solve the problem?
