Constructor Detail

• OverlappingLabels

  public OverlappingLabels(RandomAccessibleInterval<LabelingType<T>> labeling)

Method Detail

• getMatrix

  public RandomAccessibleInterval<UnsignedIntType> getMatrix()

  Get the confusion/co-occurrence matrix. Values indicate the number of pixels that are in common between the label at position x and the label at position y. For the mapping of dimension indices to labels, see getIndexedLabels().

  Returns:

  the co-occurrence matrix

• getNormalizedMatrix

  public RandomAccessibleInterval<DoubleType> getNormalizedMatrix()

  Get the normalized directional confusion matrix. Values indicate the proportion of the label at position x that is co-occurring with the label at position y. For the mapping of dimension indices to labels, see getIndexedLabels().

  Returns:

  the normalized co-occurrence matrix

• getIndexedLabels

  public List<T> getIndexedLabels()

  Get the list of labels for this confusion matrix.

  Returns:

  the list of labels in order of the matrix indices

• getPixelOverlap

  public long getPixelOverlap(T label1,
                              T label2)

  The number of pixels overlapping between two labels.

  Parameters:

  label1 - The first label

  label2 - The second label

  Returns:

  the size of the overlapping region (in pixels)

• getPixelOverlapForIndex

  public long getPixelOverlapForIndex(int index1,
                                      int index2)

  The number of pixels overlapping between two labels at the specified indices.

  Parameters:

  index1 - The index of the first label

  index2 - The index of the second label

  Returns:

  the size of the overlapping region (in pixels)

• getPartialOverlap

  public double getPartialOverlap(T ofLabel,
                                  T overlappingLabel)

  The fraction of ofLabel that overlaps with overlappingLabel. If ofLabel has size 2 and overlappingLabel has size 100, and they overlap by 1 pixel, the resulting fraction is 0.5

  Parameters:

  ofLabel -

  overlappingLabel -

  Returns:

  the overlapping fraction

• getPartialOverlapForIndex

  public double getPartialOverlapForIndex(int ofLabelIndex,
                                          int overlappingLabelIndex)

  The fraction of the label at ofLabelIndex that overlaps with the label at overlappingLabelIndex. See getPartialOverlap(Comparable, Comparable).

  Parameters:

  ofLabelIndex -

  overlappingLabelIndex -

  Returns:

  the overlapping fraction
