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
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 matrixmatrix
- 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, callsinitCoOccurrenceFrequencyMatrix(net.sourceforge.jiu.color.data.CoOccurrenceMatrix, net.sourceforge.jiu.color.data.CoOccurrenceFrequencyMatrix)
with them to initialize the new matrix, then returns it. AMemoryCoOccurrenceFrequencyMatrix
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 inputcofm
- co-occurrence matrix, will be initialized by this method- Throws:
IllegalArgumentException
- if either matrix is null or if the dimensions are not equal
