  Label all connected components in the given input image. In the output image, all background pixels will be labeled to {} and foreground components labeled as {1}, {2}, {3}, etc. where 1, 2, 3 are labels returned by labelGenerator.next(). labelGenerator.next() is called exactly n times if the input contains n connected components.

  Parameters:

  input - input image with pixels != 0 belonging to foreground.

  labeling - output labeling in which the connected components will be labeled.

  labelGenerator - produces labels for the connected components.

  se - structuring element to use. 8-connected or 4-connected (respectively n-dimensional analog)

  "Label" all connected components in the given input image. In the output image, all background pixels will be set to 0 and foreground components set to 1, 2, 3, etc.

  Note, that the output image must be cleared to 0!

  Parameters:

  input - input image with pixels > 0 belonging to foreground.

  output - output image, must be filled with 0.
