title: Emgu CV color detection and replace
body: <p>I'm working on veins detection from image using emgu CV and I have few questions. Is there any simple way to detect color or range of colors? Is there a simple way to replace this color with another (e.g. average color of the image)? How can I achive that without degrading the performance?</p>
  
  <p>Thanks in advance!</p>
