• Labelings

  public Labelings()

Method Detail

• getLabelingMapping

  public static <T> LabelingMapping<T> getLabelingMapping(RandomAccessibleInterval<LabelingType<T>> labeling)

  Get a LabelingMapping from any RandomAccessibleInterval on LabelingType.

  Parameters:

  labeling - The label image

  Returns:

  mapping of indices to sets of labels

• remapLabels

  public static <T,U,I extends IntegerType<I>> ImgLabeling<U,I> remapLabels(ImgLabeling<T,I> labeling,
                                                                            Function<T,U> function)

  Create a new ImgLabeling from an input labeling, with the labels transformed according to the provided Function. The mapping function needs to be an injective function (i.e. no duplicates are allowed in the result of the mapping), otherwise an IllegalArgumentException will be thrown.

  Parameters:

  labeling - The ImgLabeling to be transformed

  function - The Function providing the mapping from input to output labels

  Returns:

  the transformed ImgLabeling

• remapLabels

  public static <T,U,I extends IntegerType<I>> ImgLabeling<U,I> remapLabels(ImgLabeling<T,I> labeling,
                                                                            Map<T,U> mapping)

  Create a new ImgLabeling from an input labeling, with the labels transformed according to the provided Map. The map needs to be injective/bijective (i.e. no duplicates are allowed in the result of the mapping), otherwise an IllegalArgumentException will be thrown.

  Parameters:

  labeling - The ImgLabeling to be transformed

  mapping - The Map mapping input to output labels

  Returns:

  the transformed ImgLabeling

• getOccurringPixelSets

  public static <T,I extends IntegerType<I>> Set<I> getOccurringPixelSets(ImgLabeling<T,I> img)

  Return a Set of occurring pixel values in the ImgLabeling index image.

  Type Parameters:

  T - The type of labels assigned to pixels

  I - The pixel type of the backing image

  Parameters:

  img - Image labeling from which to extract the occurring pixel values

  Returns:

  Set of occurring pixel values

• hasIntersectingLabels

  public static <T,I extends IntegerType<I>> boolean hasIntersectingLabels(ImgLabeling<T,I> img)

  Check if the image labeling img has intersecting labels. Two labels intersect if there is at least one pixel in the image labeled with both labels.

  Type Parameters:

  T - The type of labels assigned to pixels

  I - The pixel type of the backing image

  Parameters:

  img - Image labeling

  Returns:

  True if the image labeling has intersecting labels, false otherwise.
