title: Copying image from a mask
body: <p>I have 2 images, the 1st image is the original image and the 2nd image is the mask.
  <a href="https://i.stack.imgur.com/i4AJV.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/i4AJV.jpg" alt="Original image"></a>
  <a href="https://i.stack.imgur.com/SKlce.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/SKlce.jpg" alt="Mask"></a></p>
  
  <p>How can I apply the mask as the opacity or alpha channel for the first image using EmguCV in C#?</p>
