MandelEllis

public MandelEllis(Matrix covarMatrix,
                   Matrix mean)

"Gaussian Mixture Model for Mandel / Ellis algorithm" This class holds the features needed for the Mandel Ellis algorithm: One full covariance matrix, and the mean of all MFCCS.

MandelEllis

protected MandelEllis()

Method Detail

getAsArray

public double[] getAsArray()

Returns the fluctuation pattern matrix as a double array.

Specified by:

getAsArray in class AudioFeature

Returns:

double[] the fluctuation pattern matrix, row packed

getDistance

public double getDistance(AudioFeature f)

Description copied from class: AudioFeature

Measures the similarity/dissimilarity of two audio streams characterized by two audio features.

Specified by:

getDistance in class AudioFeature

Parameters:

f - AudioFeature another audio feature of the same type

Returns:

double the distance between the two audio streams

writeXML

public void writeXML(XMLStreamWriter writer)
              throws IOException,
                     XMLStreamException

Writes the xml representation of this object to the xml output stream.

There is the convention, that each call to a writeXML() method results in one xml element in the output stream.

Specified by:

writeXML in interface XMLSerializable

Parameters:

writer - XMLStreamWriter the xml output stream

Throws:

IOException - raised, if there are any io troubles

XMLStreamException - raised, if there are any parsing errors

readXML

public void readXML(XMLStreamReader parser)
             throws IOException,
                    XMLStreamException

Reads the xml representation of an object form the xml input stream.

There is the convention, that readXML() starts parsing by checking the start tag of this object and finishes parsing by checking the end tag. The caller has to ensure, that at method entry the current token is the start tag. After the method call it's the callers responsibility to move from the end tag to the next token.

Specified by:

readXML in interface XMLSerializable

Parameters:

parser - XMLStreamReader the xml input stream

Throws:

IOException - raised, if there are any io troubles

XMLStreamException - raised, if there are any parsing errors
