                                                                           Image<BitType> img,
                                                                           Iterator<T> names)
                                                                    throws NoSuchElementException

  Label all connected components in the given image using an 8-connected structuring element or it's N-dimensional analog (connect if touching along diagonals as well as +/- one element in any direction).

  Type Parameters:

  T - the type of the labels to apply

  Parameters:

  labeling - Assign labels to this labeling space

  img - a binary image where true indicates parts of components

  names - supplies names for the different components as needed

  Throws:

  NoSuchElementException - if there are not enough names

                                                                           Image<BitType> img,

  Label all connected components in the given image using an arbitrary structuring element.

  Type Parameters:

  T - the type of the labels to apply

  Parameters:

  labeling - Assign labels to this labeling space

  img - a binary image where true indicates parts of components

  names - supplies names for the different components as needed

  structuringElement - an array of offsets to a pixel of the pixels which are considered connected. For instance, a 4-connected structuring element would be "new int [][] {{-1,0},{1,0},{0,-1},{0,1}}".

  Throws:

  NoSuchElementException - if there are not enough names

• getStructuringElement

  public static int[][] getStructuringElement(int dimensions)

  Return an array of offsets to the 8-connected (or N-d equivalent) structuring element for the dimension space. The structuring element is the list of offsets from the center to the pixels to be examined.

  Parameters:

  dimensions -

  Returns:

  the structuring element.

• getIntegerNames

  public static Iterator<Integer> getIntegerNames(int start)

  Return an iterator that (endlessly) dispenses increasing integer values for labeling components.

  Parameters:

  start -

  Returns:

  an iterator dispensing Integers
