title: Convert ColorSpaces using OpenCv in Python
body: <p>How do I convert an image within BGRA color space to HSV and BGRA to YCbCR? I only know convertion from BGR and not BGRA. Is the approach different or the same?</p>
  
  <pre><code>hsv_image = cv2.cvtColor(frame, cv2.COLOR_BGR2HSV)
  ycrcb_image = cv2.cvtColor(frame, cv2.COLOR_BGR2YCrCb)
  </code></pre>
  
  <p>Your help will be very much appreciated.</p>
