Class DetectionTracker

java.lang.Object

likelihoodDetectionModule.thresholdDetector.DetectionTracker

public class DetectionTracker
extends java.lang.Object

This class is used to track statistics about a running detection. Currently it remembers the startTime (in ms since 01-01-1970), the startSample number. Then it calculates the duration (in samples), and uses two CurvePeakTracker objects to track the peak, time, and sample number of the peak in the raw energy, as well as the peak in the SNR
