title: Difference between OpenCV type CV_32F and CV_32FC1
body: <p>I would like to know if there is any difference between OpenCV types CV_32F and CV_32FC1? 
  I already know that 32F stands for a "32bits floating point" and C1 for "single channel", but further explanations would be appreciated.</p>
  
  <p>If yes, how are they different / which one should I use in which specific cases? As you might know that openCV types can get very tricky...</p>
  
  <p>Thank you all in advance for your help!</p>
