Description
Whenever, I try EM::COV_MAT_DIAGONAL to train my Gaussian Mixture models, the covariance matrix turns out to be all zeros. However, using EM::COV_MAT_GENERIC returns covariance matrix as expected.
I am using r8282 compiled using VS 2008 on Windows 7.

Thanks a lot for the report. The problem was in cv::Mat::diag(). It was fixed in r8385.
