OpenCV naming convensions

• Matrix data types:

  CV_[bit_depth](S|U|F)C[number_of_channels]
  S = Signed integer
  U = Unsigned integer
  F = Float 
  

  E.g.: CV_8UC1 means an 8-bit unsigned single-channel matrix,
          CV_32FC2 means a 32-bit float matrix with two channels.


• Image data types:

  IPL_DEPTH_[bit_depth](S|U|F)

  E.g.: IPL_DEPTH_8U means an 8-bit unsigned image.
          IPL_DEPTH_32F means a 32-bit float image.
  

Note that in the image data types, the depth and number of channels are specified separately.
