title: Opencv: Get Expectation Maximization (EM) using Gaussian Mixture Model ( GMM)
body: <p>I am trying to use GMM to find expectation maximization of different colors in a video frame. Then according to that, I will determine which is the dominant color. </p>
  
  <p>For that, my problem is how can I perform GMM based EM to get and compare those expectations for different colors?</p>
