prepDelphinIDModel

public static DelphinIDTest.DelphinIDWorkerTest prepDelphinIDModel(String modelPath)

getWhistleContoursMAT

public static ArrayList<AbstractWhistleDataUnit> getWhistleContoursMAT(String filePath)

Load whistle contours from a MAT file. ()

Parameters:

filePath - - the file path.

Returns:

a list of whistle contour objects from the mat file.

getWhistleContoursMAT

public static ArrayList<AbstractWhistleDataUnit> getWhistleContoursMAT(us.hebi.matlab.mat.types.Struct whistlesStruct,
 double fftLen,
 double fftHop,
 double sampleRate)

Load whistle contours from a MATLAB struct

Parameters:

whistlesStruct - - a struct containing a list of whistle contours

fftLen - - the fft length in samples

fftHop - - the fft hop in samples.

sampleRate - - the sample rate in samples per second.

Returns:

a list of whistle contour objects from the struct.

segmentWhsitleData

public static ArrayList<SegmenterDetectionGroup> segmentWhsitleData(ArrayList<AbstractWhistleDataUnit> whistles,
 long dataStartMillis,
 double segLen,
 double segHop)

Segment the detections into groups. Note that segments are overlaps so each whistle may belong to multiple segments.

Parameters:

whistles - - a list of whistles - not necessarily sorted by time.

dataStartMillis - - the start time of the data in millis i.e. where the first segment starts.

segLen - - the segment size in milliseconds.

segHop - - the segment hop in milliseconds.

Returns:

groups of data units within each segment.

main

public static void main(String[] args)
