Class TextureAnalysis

      extended bynet.sourceforge.jiu.color.analysis.TextureAnalysis

public class TextureAnalysis
extends Operation

This class determines a number of properties for a given co-occurrence matrix. The only input parameter is a mandatory co-occurrence matrix object to be specified using setMatrix(net.sourceforge.jiu.color.data.CoOccurrenceMatrix). Then process() must be called. After that, the various properties can be retrieved using the corresponding get methods, e.g. getContrast(), getEnergy() etc.

The following resources were helpful when creating this class:

Constructor Detail

TextureAnalysis

public TextureAnalysis()
Method Detail

getContrast

public int getContrast()
Returns the contrast value determined in process(). Also called inertia.


getCorrelation

public double getCorrelation()
Returns the correlation determined in process().


getDissimilarity

public int getDissimilarity()
Returns the dissimilarity value determined in process().


getEnergy

public int getEnergy()
Returns the energy value determined in process().


getEntropy

public double getEntropy()
Returns the entropy value determined in process().


getHomogeneity

public double getHomogeneity()
Returns the homogeneity value determined in process(). Also called inverse difference moment.


getSum

public int getSum()
Returns the sum of all entries in the matrix.


isSymmetrical

public boolean isSymmetrical()

process

public void process()
             throws MissingParameterException
Run over the input matrix and determine contrast, energy, entropy and homogeneity of that matrix.

Overrides:
process in class Operation
Throws:
MissingParameterException - if no co-occurrence matrix was provided using setMatrix(net.sourceforge.jiu.color.data.CoOccurrenceMatrix)

setMatrix

public void setMatrix(CoOccurrenceMatrix m)
Sets the matrix to be used by this operation to the argument value.

Parameters:
m - the matrix for which the various properties will be computed
