DetectOscillations(Double[], Double, Double, Double, Double, Double, Double, out Double[], out Double[])

Currently this method is called by only one species recognizer - LitoriaCaerulea.

Declaration

public static void DetectOscillations(double[] ipArray, double framesPerSecond, double decibelThreshold, double dctDuration, double minOscFreq, double maxOscFreq, double dctThreshold, out double[] dctScores, out double[] oscFreq)

Parameters

Type	Name	Description
Double[]	ipArray	an array of decibel values.
Double	framesPerSecond	the frame rate.
Double	decibelThreshold	Ignore frames below this threshold.
Double	dctDuration	Duration in seconds of the required DCT.
Double	minOscFreq	minimum oscillation frequency.
Double	maxOscFreq	maximum oscillation frequency.
Double	dctThreshold	Threshold for the maximum DCT coefficient.
Double[]	dctScores	an array of dct scores.
Double[]	oscFreq	an array of oscillation frequencies.
