Method Detail

• createCoOccurrenceMatrix

  public static CoOccurrenceMatrix createCoOccurrenceMatrix​(Gray16Image image)

  Create a co-occurrence matrix for a 16 bit grayscale image.

  Parameters:

  image - the image for which the matrix is created

  Returns:

  the resulting matrix

  Since:

  0.15.0

• createCoOccurrenceMatrix

• createCoOccurrenceMatrix

  public static CoOccurrenceMatrix createCoOccurrenceMatrix​(Paletted8Image image)

• createCoOccurrenceMatrix

  public static CoOccurrenceMatrix createCoOccurrenceMatrix​(IntegerImage image,
                                                            int channelIndex)

• initCoOccurrenceMatrix

  public static void initCoOccurrenceMatrix​(IntegerImage image,
                                            int channelIndex,
                                            CoOccurrenceMatrix matrix)

  Initializes a co-occurrence matrix from the input image, using the direct four neighbor pixels. The number of entries in the palette of the argument image must be equal to the dimension of the argument matrix.

  Parameters:

  image - the image that will be used to initialize the matrix

  matrix - the matrix that will first be cleared and then initialized from the image

  Throws:

  IllegalArgumentException - if at least one of the arguments is null or if the palette size is not equal to the matrix dimension

• createCoOccurrenceFrequencyMatrix

  public static CoOccurrenceFrequencyMatrix createCoOccurrenceFrequencyMatrix​(CoOccurrenceMatrix A)

  Creates a new co-occurrence frequency with the same dimension as the argument co-occurrence matrix, calls initCoOccurrenceFrequencyMatrix(net.sourceforge.jiu.color.data.CoOccurrenceMatrix, net.sourceforge.jiu.color.data.CoOccurrenceFrequencyMatrix) with them to initialize the new matrix, then returns it. A MemoryCoOccurrenceFrequencyMatrix is created.

  Parameters:

  A - the co-occurrence matrix from which the resulting matrix will be initialized

  Returns:

  the newly-created co-occurrence frequency matrix

  Throws:

  IllegalArgumentException - if the argument matrix is null

• initCoOccurrenceFrequencyMatrix

  public static void initCoOccurrenceFrequencyMatrix​(CoOccurrenceMatrix A,
                                                     CoOccurrenceFrequencyMatrix cofm)

  Initializes a co-occurrence frequency matrix from a co-occurrence matrix. The two argument matrices must be non-null and have the same dimension.

  Parameters:

  A - co-occurrence matrix used as input

  cofm - co-occurrence matrix, will be initialized by this method

  Throws:

  IllegalArgumentException - if either matrix is null or if the dimensions are not equal
