title: RGB in OpenCV. What does it mean?
body: <p>Assume we are reading and loading an image using OpenCV from a specific location on our drive and then we read some pixels values and colors, and lets assume that this is a <strong>scanned image</strong>.</p>
  
  <p>Usually if we open scanned image we will notice some differences  between the printed image (before scanning) and the image if we open it and see it on the display screen.</p>
  
  <p><strong>The question is:</strong></p>
  
  <p>The values of the pixels colors that we get from OpenCV. Are they according to our display screen color space or we get exactly the same colors we have in the scanned image (printed version) ??</p>
