Python implementation of Expectation-Maximization algorithm (EM) for Gaussian Mixture Model (GMM). Code for GMM is in GMM.py. It's very well documented on how to use it on your data. For an example and visualization for 2D set of points, see the notebook EM_for_2D_GMM.ipynb. Requirements: Numpy;
Yes, its seems like EM in OpenCV for Python is not very well defined. I have used sklearn library which provides GMM model implementation and it works perfectly.
