我正在尝试编译此c ++应用程序
int main ()
{
Mat frame;
Mat back;
Mat fore;
VideoCapture cap1;
cap1.open(0); /*to capture from camera*/
cv::Ptr<BackgroundSubtractorMOG> pMOG = createBackgroundSubtractorMOG();
cv::Ptr<BackgroundSubtractorMOG2> pMOG2 = createBackgroundSubtractorMOG2();
pMOG2->setNMixtures(10);
vector < vector < Point > >contours;
namedWindow ("Frame");
int i=0;
for (;;)
{
cap1 >> frame;
pMOG2->operator()(frame, fore);
pMOG2->getBackgroundImage (back);
erode (fore, fore, cv::Mat ());
erode (fore, fore, cv::Mat ());
dilate (fore, fore, cv::Mat ());
dilate (fore, fore, cv::Mat ());
dilate (fore, fore, cv::Mat ());
findContours (fore, contours, CV_RETR_EXTERNAL,CV_CHAIN_APPROX_NONE);
drawContours (frame, contours, -1, Scalar (255, 255, 255), 1);
Scalar color = Scalar(200,200,200);
int a=0;
vector<Rect> boundRect( contours.size() );
for( int i = 0; i < contours.size(); i++ )
{
boundRect[i] = boundingRect( contours[i] );
}
for( i = 0; i< contours.size(); i++ )
{
if(boundRect[i].width>=40 || boundRect[i].height>=40)//eliminates small boxes
{
a=a+(boundRect[i].height)*(boundRect[i].width);
}
// cout<<"Net contour area is "<<a<<"\n";
if(a>=int(frame.rows)*int(frame.cols)/2)//change denominator as per convenience
{
putText(frame,"Tampering",Point(5,30),FONT_HERSHEY_SIMPLEX,1,Scalar(0,255,255),2);
cout<<"\a";
}
}
imshow ("Frame", frame);
waitKey(10);
}
我在编译时遇到以下错误
Tampering.cpp:27:21:错误:'类cv :: BackgroundSubtractorMOG2'具有 没有名为“ operator()”的成员 pMOG2-> operator()(frame,fore);
我的opencv版本3.3.0
预先感谢
答案 0 :(得分:1)
首先,感谢您订阅我的存储库:https://github.com/SaranshKejriwal/Tampering-Detection/blob/master/Tampering%20main/Tampering.cpp
在我的案例中,我使用过openCV 2.4.5,它在BackgroundSubtractorMOG2类中具有operator()方法。
由于您使用的是openCV 3.3.0,因此建议您查看文档,以确认此方法仍然存在
