whistleClassifier
Class WhistleClassifierProcess

java.lang.Object
  PamguardMVC.PamProcess
      whistleClassifier.WhistleClassifierProcess

All Implemented Interfaces:

Annotator, PamObserver

public class WhistleClassifierProcess
extends PamProcess

Whistle Classifier process

Receives whistles from either whistle detector. Fragments them and either stores the fragments for later training or builds up information on many fragments and then classifies when it's got enough.

Keeps a list or recent whistle times so that it can clear the store if the whistle rate drops too low.
