RoccaClassifier

public RoccaClassifier(RoccaProcess roccaProcess)

Create RoccaClassifier object for RoccaProcess

Parameters:

roccaProcess -

Method Detail

classifyContour

public void classifyContour(RoccaContourDataBlock rcdb)

NO LONGER USED, since the addition of the RoccaRFModel object

Classifies the passed contour

Checks to make sure a classifier has been loaded, then runs the setAttributes method to match the passed contour to the parameter list expected by the classifier. Once the attribute vector has been created, the classifier is run and the results are saved to the datablock's classifiedAs field.

Parameters:

rcdb - RoccaContourDataBlock to be classified

classifyContour2

public void classifyContour2(RoccaContourDataBlock rcdb)

Classifies the passed contour

Checks to make sure a classifier has been loaded, then calls the RoccaRFModel object to classify the contour. Clears the rcdb tree votes first, since the RccaRFModel object adds to the votes as it iterates through the different classifiers

Parameters:

rcdb - RoccaContourDataBlock to be classified

setUpClassifier

public boolean setUpClassifier()

Loads the Classifier model from the file specified in RoccaParameters

Returns:

boolean flag indicating success or failure of load

setAttributes

public weka.core.DenseInstance setAttributes(RoccaContourDataBlock rcdb)

Sets up the available datablock fields to match the classifier model

Compares the fields in the passed RoccaContourDataBlack to the fields required for the classifier. If any fields are missing, an error is displayed and the method returns false. If all the fields are available, an Instance is created matching the order of the datablock fields to the order of the classifier fields.

Parameters:

rcdb - RoccaContourDataBlock to be classified

Returns:

Instance containing the values of the rcdb parameters that match the classifier attributes

setAttributes

public weka.core.DenseInstance setAttributes(RoccaContourDataBlock rcdb,
                                    weka.core.Instances trainedDataset)

Sets up the available datablock fields to match the classifier model

Compares the fields in the passed RoccaContourDataBlack to the fields required for the classifier. If any fields are missing, an error is displayed and the method returns false. If all the fields are available, an Instance is created matching the order of the datablock fields to the order of the classifier fields.

Parameters:

rcdb - RoccaContourDataBlock to be classified

trainedDataset - Instances containing the training data set

Returns:

Instance containing the values of the rcdb parameters that match the classifier attributes

areFieldsSet

public boolean areFieldsSet()

setFieldsSet

public void setFieldsSet(boolean fieldsSet)

getClassifierSpList

public java.lang.String[] getClassifierSpList()

returns list of species classes. If variable is null, creates the list first

Returns:

String[] list of species

clearSpeciesList

public void clearSpeciesList()

Parameters:

speciesList - the speciesList to set

generateSpList

public java.lang.String[] generateSpList()

generates list of species classes.

Returns:

String[] list of species

generateSpList_orig

public java.lang.String[] generateSpList_orig()

generates list of species classes. If there are two classifiers, both lists will be combined into single list based on trigger class NOTE: this method is the original version, which loaded 2 separate classifier files. No longer used since RoccaRFModel class has been implemented, but I hate to delete the code...

Returns:

String[] list of species
