I'm having trouble using cv::sort
functionality in C++ API of OpenCV.
I'm trying to sort cv::Mat
contents in OpenCV using
cv::sort(InputArray src, OutputArray dst, int flags);
The following code gives me a compilation error. I'm not sure whats wrong with this code:
using namespace std;
using namespace cv;
int main(int argc, char** argv)
{
Mat matrix(5,5,CV_32F,Scalar(0)),m;
randn(matrix, 2.00, 1.00);
cout<<"before sorting:\n"<<matrix<<endl;
sort(matrix, m, CV_SORT_EVERY_ROW + CV_SORT_ASCENDING);
cout<<"after sorting:\n"<<m<<endl;
return 0;
}
You have to use cv::sort() rather than sort(), even you are using namespace cv. That is because C++ has an implementation of sort() in namespace std and simply using sort() will make a conflict.
