Class Smoothing

java.lang.Object

stream.AbstractProcessor

stream.image.AbstractImageProcessor

stream.image.filters.Smoothing

All Implemented Interfaces:

ImageProcessor, stream.Processor, stream.StatefulProcessor

public class Smoothing
extends AbstractImageProcessor

The Smooting Operator is a filter to reduce the noise in an input image. Each pixel gets replaced by the average of pixels in a square window surrounding this pixel.

Method Detail

getWindowSize

public Integer getWindowSize()

Returns:

the windowSize

setWindowSize

public void setWindowSize(Integer windowSize)

Parameters:

windowSize - the windowSize to set

setWeighted

public void setWeighted(Boolean weighted)

getOutput

public String getOutput()

Returns:

name The name/key under which the smoothed image is stored.
