KernelSmoothing

Class KernelSmoothingProcess

java.lang.Object

PamguardMVC.PamProcess

KernelSmoothing.KernelSmoothingProcess

All Implemented Interfaces:

PamObserver, ProcessAnnotator

public class KernelSmoothingProcess
extends PamProcess

Author:

Doug Gillespie Class to smooth out a spectrogram using a Gaussian smoothing kernel Currently fixed to be 3 by 3, but could have others in the future. 29 October, 2008, Added phase information back into smoothed output so that whistle detector can use the smoothed data to estimate bearings to detected whistles
