Hi. I have tried a people detector from here:
beside it doesn't detect very well the people inside of video, the program takes 99% CPU load … why ? It is normal ?
Here is the sample code:
VideoCapture cap;
cap.open(_T("C:\\Flaviu\\Cat Calls Walking in Street.avi"));
Detector detector;
Mat frame;
for(;;)
{
cap >> frame;
if (frame.empty())
{
cout << "Finished reading: empty frame" << endl;
break;
}
int64 t = getTickCount();
vector<Rect> found = detector.detect(frame); // <------------- this line takes 99% CPU load !!!
t = getTickCount() - t;
// show the window
{
ostringstream buf;
buf << "Mode: " << detector.modeName() << " ||| "
<< "FPS: " << fixed << (getTickFrequency() / (double)t);
putText(frame, buf.str(), Point(10, 30), FONT_HERSHEY_PLAIN, 2.0, Scalar(0, 0, 255), 2, LINE_AA);
}
for (vector<Rect>::iterator i = found.begin(); i != found.end(); ++i)
{
Rect &r = *i;
detector.adjustRect(r);
rectangle(frame, r.tl(), r.br(), cv::Scalar(0, 255, 0), 2);
}//*/
imshow("People detector", frame);
// interact with user
const char key = (char)waitKey(30);
if (key == 27 || key == 'q') // ESC
{
cout << "Exit requested" << endl;
break;
}
else if (key == ' ')
{
detector.toggleMode();
}
}
I have done soething wrong here ?
