title: what is the function to find otsu threshold in emgu cv?
body: <p>I don't need the thresholded image. I want the threshold. I found this in OpenCV.</p>
  
  <pre><code>cv::threshold( orig_img, thres_img, 0, 255, CV_THRESH_BINARY+CV_THRESH_OTSU );
  </code></pre>
  
  <p>Is there an equivalent in EmguCv. Thanks in advance.</p>
  
  <p>PS. I need to use this threshold for canny edge detector</p>
