KernelSmoothing
Class KernelSmoothingProcess

java.lang.Object
  PamguardMVC.PamProcess
      KernelSmoothing.KernelSmoothingProcess

All Implemented Interfaces:

Annotator, PamObserver

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

Method Detail

noteNewSettings

public void noteNewSettings()

Specified by:

noteNewSettings in interface PamObserver

Overrides:

noteNewSettings in class PamProcess

setParentDataBlock

public void setParentDataBlock(PamDataBlock newParentDataBlock)

Description copied from class: PamProcess

Set a parent data block with the default options of rethreading if set

Overrides:

setParentDataBlock in class PamProcess

Parameters:

newParentDataBlock - source data block.

setupProcess

public void setupProcess()

Description copied from class: PamProcess

called for every process once the systemmodel has been created. this is a good time to check out and find input data blocks and similar tasks.

Overrides:

setupProcess in class PamProcess

Specified by:

pamStart in class PamProcess

pamStop

public void pamStop()

Description copied from class: PamProcess

Stops the process.

Specified by:
