Method Detail

extractFeatures

boolean extractFeatures()
                        throws FeatureExtractionException

Abstract feature extraction routine. Requires an IPreprocessing to provide the sample data.

Returns:

boolean true if there were features extracted, false otherwise

Throws:

FeatureExtractionException - if there was an error while extracting features

extractFeatures

boolean extractFeatures(double[] padSampleData)
                        throws FeatureExtractionException

Abstract feature extraction routine.

Parameters:

padSampleData - the sample to extract features from

Returns:

boolean true if there were features extracted, false otherwise

Throws:

FeatureExtractionException - if there was an error while extracting features

Since:

0.3.0.6

getFeaturesArray

double[] getFeaturesArray()

Allows retrieval of the features.

Returns:

array of features (double values)

getPreprocessing

IPreprocessing getPreprocessing()

Retrieves inner preprocessing reference.

Returns:

the preprocessing reference

Since:

0.3.0.4

setPreprocessing

void setPreprocessing(IPreprocessing poPreprocessing)

Allows setting the source preprocessing module.

Parameters:

poPreprocessing - the preprocessing object to set

Since:

0.3.0.4
