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.

Smoothing

public Smoothing()

Method Detail

getWindowSize

public Integer getWindowSize()

Returns:

the windowSize

setWindowSize

@Parameter(description="Sets the window size. The window size determines the neighboring pixels for each pixel, that are averaged. A windowSize of 3 means that 3 times 3 = 9 pixels are taken into account.")
public void setWindowSize(Integer windowSize)

Parameters:

windowSize - the windowSize to set

setWeighted

@Parameter(description="If a weighted smoothing technique is selected, neighbors closer to the pixel to be smoothend are counted with a higher weight.")
public void setWeighted(Boolean weighted)

getOutput

public String getOutput()

Returns:

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

setOutput

@Parameter(description="The name/key of the output image is stored. If this name equals the name of the input image, the input image is going to be overwritten.")
public void setOutput(String output)

Setter for the Parameter Output

Parameters:

output - The name/key under which the smoothed Image is stored. If this name equals the name of the input image, the input image is going to be overwritten.

init

public void init(stream.ProcessContext ctx)
          throws Exception

Specified by:

process

public stream.Data process(stream.Data item,
                  ImageRGB img)
