Method Summary

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.
static CoOccurrenceMatrix	createCoOccurrenceMatrix(Gray8Image image)
static CoOccurrenceMatrix	createCoOccurrenceMatrix(IntegerImage image, int channelIndex)
static CoOccurrenceMatrix	createCoOccurrenceMatrix(Paletted8Image image)
static void	initCoOccurrenceFrequencyMatrix(CoOccurrenceMatrix A, CoOccurrenceFrequencyMatrix cofm) Initializes a co-occurrence frequency matrix from a co-occurrence matrix.
static void	initCoOccurrenceMatrix(IntegerImage image, int channelIndex, CoOccurrenceMatrix matrix) Initializes a co-occurrence matrix from the input image, using the direct four neighbor pixels.

Method Detail

createCoOccurrenceMatrix

public static CoOccurrenceMatrix createCoOccurrenceMatrix(Gray8Image image)

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
