title: break image into CMYK channels with OpenCV in python
body: <p>I am trying to take an image (as a test I am using a copy of the Windows XP field wallpaper) and break it into 4 images each being one of the CMYK channels. I want to have these each saved so I can use them later.</p>
  <p>I cannot seem to find anything that seems to work right.</p>
  <p>Would anyone be able to at least show me where to look because I can't seem to find a decent explanation that I am able to follow.</p>
