Methods

DetectBarsInTheRowsOfaMatrix(Double[,], Double, Int32)

TODO THis method could eventually be deleted. It has been replaced by the other methods below. Amongst other things, the term "periodicity" is used incorrectly in this method. It actually refers to the "harmonic interval". This method assumes the matrix is derived from a spectrogram rotated so that the matrix rows are spectral timeframes of a spectrogram.

Declaration

public static Tuple<double[], double[]> DetectBarsInTheRowsOfaMatrix(double[, ] m, double threshold, int zeroBinCount)

Parameters

Type	Name	Description
Double[,]	m
Double	threshold
Int32	zeroBinCount

Returns

Type	Description
Tuple<Double[], Double[]>

DetectHarmonicsInSonogramMatrix(Double[,], Double, Int32)

TODO TODO this method could be deleted. It is called only by a method to detect crow calls. THis is long since superceded. A METHOD TO DETECT HARMONICS IN THE ROWS of the passed portion of a sonogram. This method assume the matrix is derived from a spectrogram rotated so that the matrix rows are spectral columns of sonogram. Was first developed for crow calls. First looks for a decibel profile that matches the passed call duration and decibel loudness. Then samples the centre portion for the correct harmonic period.

Declaration

public static Tuple<double[], double[], double[]> DetectHarmonicsInSonogramMatrix(double[, ] m, double dBThreshold, int callSpan)

Parameters

Type	Name	Description
Double[,]	m	data matrix.
Double	dBThreshold	Minimum sound level.
Int32	callSpan	Minimum length of call of interest.

Returns

Type	Description
Tuple<Double[], Double[], Double[]>	a tuple.
