SweepClassifierWorker

public SweepClassifierWorker(ClickControl clickControl,
 SweepClassifier sweepClassifier)

Method Details

identify

public ClickIdInformation identify(ClickDetection click)

Classifiy the click based on a sequential list of clicks classifiers. The click is identified as the first sweep classifier it passes in the list. If checkAllClassifiers is enabled in the sweep params then the click is tested by all classiifers and a list of passed classifiers is saved in the ClickIdInformation.

Parameters:

click - - the click to test

Returns:

classification informaiton.

testZeroCrossingStat

public boolean testZeroCrossingStat(ZeroCrossingStats zcStat,
 SweepClassifierSet scs)

Test whether the zero crossing statistics pass sweep classifier tests

Parameters:

zcStat - - the zero crossings statistics.

scs - - sweep classifier parameters.

Returns:

true if passed.

getLengthData

public int[][] getLengthData(ClickDetection click,
 SweepClassifierSet scs)

Creates a 2D array of length data[channels][start/end]

Will only call getLengthData if it really has to. really has to.

2017/11/24 added synchronized keyword

Parameters:

click - click

scs - classifier settings

createLengthData

public static int[][] createLengthData(ClickDetection click,
 int nChannels,
 double lengthdB,
 int lengthSmoothing)

Creates a 2D array of length data[channels][start/end]

Parameters:

click - - the click detection

nChannels - - the number of channels to process

lengthdB - - the dB drop for peak finding

lengthSmoothing - - the number of bins to smooth waveform for length calculation

Returns:

2D array of length compesnated click bin positions to use for modified measurements.

createLengthData

public static int[][] createLengthData(ClickDetection click,
 int nChannels,
 double lengthdB,
 int lengthSmoothing,
 boolean enableFFTFilter,
 FFTFilterParams fftFilterParams)

Creates a 2D array of length data[channels][start/end]

Parameters:

click - - the click detection

nChannels - - the number of channels to process

lengthdB - - the dB drop for peak finding

lengthSmoothing - - the number of bins to smooth waveform for length calculation

enableFFTFilter - - true to use filter

fftFilterParams - - the filter params- this is null if no filter is used.

Returns:

2d array of length compensated click bin positions to use for modified measurements.

getZeroCrossingStats

public ZeroCrossingStats[] getZeroCrossingStats(ClickDetection click)

Returns the zeroCrossingStats variable, used as an identifier in the Rocca interface. 2014/07/25 MO

Parameters:

click - the Click Detection

Returns:

resetLengthData

public void resetLengthData()

Clear the lengthData parameter. Required when Rocca runs multiple analysis on the same clicks. Once the length data is calculated, it's no longer recalculated even when a different click is being analyzed. added by MO 2015/06/04 2017/11/24 added synchronized keyword
