I am using cv::EM to train the GMMs. Everything works fine except when I want to get the co-variance matrix I got a Debug Assertion Failed.
The code is:
cout << "Test the EM algorithm in Opencv" << endl;
cv::EM em(5);
em.train(training_set);
if (em.isTrained())
{
cout << "Finished trainging EM" << endl;
const cv::Mat &weights = em.get<cv::Mat>("weights");
const cv::Mat &Means = em.get<cv::Mat>("means");
const vector<cv::Mat> &Covs = em.get<vector<cv::Mat>>("covs");
}
system("pause");
and the error message is:
Debug Assertion Failed!
Program: D:\Kinect test\GMM\GMM\x64\Debug\GMM.exe File: f:\dd\vctools\crt\crtw32\misc\dbgheap.c Line: 1424
Expression: _pFirstBlock == pHead

I am using opencv2.4.13 and visual studio 2015. I had read lots of documents, but none of them helps. Please help me with that. Thank you!
