title: Converting image from RGB to HSV color space
body: <p>I couldn't find such function (i.e.  <code>RGB_to_HSV()</code>) in <code>Scipy</code> or <code>Matplotlib's</code> documentations, and Google doesn't show pointers, except <code>ActiveState</code> recipe which demonstrates <code>rgb2hsv</code> function, though not usable on <code>Numpy</code> array as is.</p>
  
  <p>Does someone know of a shortcut?</p>

  <p>Edit: Sorry, just found <code>matplotlib.colors.rgb_to_hsv()</code> which is exactly what I was looking for. Should I delete this question?</p>
