Univariate GMM esitimation might be wrong!

[subhashis]

When checked with the GMM estimation of OpenCV lib the corresponding edda version gives very different results (possibly wrong). The weights of all the Gaussian components seems to have equal values.

If we give the program different initial guess, it sometime return the correct results.
(Our current version gives the same initial guess every time).
We should look for the standard way to solve this problem.

Note: k-mean could be one way to have better initial guess

One option is to remove the univariate GMM and directly use multivarite GMM
