title: Opencv: Converting hue image to RGB image
body: <p>I am trying to show the hue component of the image from my webcam.  I have split apart the image into the hue component but I can't figure out how to show the hue component as the pure colors.  For example if one pixel of the image was B=189 G=60 R=60 then in HSV, H=0.  I don't want the draw image to be the the gray values of hue but the RGB equivalent of the hue or H=0 -> B=0 G=0 R=255</p>
  
  <pre><code>IplImage *image, *imageHSV, *imageHue;
  image = cvQueryFrame(capture); //image from webcam
  imageHSV = cvCreateImage( cvGetSize(image), IPL_DEPTH_8U, 3 );
  imageHue = cvCreateImage( cvGetSize(image), IPL_DEPTH_8U, 1 );
  cvCvtColor( image, imageHSV, CV_BGR2HSV );
  cvSplit( imageHSV, imageHue, 0, 0, 0 );
  </code></pre>
  
  <p>I have a feeling there is a simple solution so any help is appreciated.</p>
