public class GaussianBlur
extends BoxBlur

GaussianBlur - a fast approximation of Gaussian Blur performed by multiple passes of a Box Blur. Typically 3 passes are used, which is ~97% of a "real" Gaussian Blur.

Constructor Detail

GaussianBlur

public GaussianBlur(int radius)

Creates a new Gaussian Blur of the specified radius. Uses 3 Box Blur passes.

Parameters:

radius - radius of the blur

GaussianBlur

public GaussianBlur()

Creates a new Gaussian Blur of radius 5.

GaussianBlur

public GaussianBlur(int radius,
                    int numPasses)

Creates a new Gaussian Blur of the specified radius and number of Box Blur passes.

Parameters:

radius - radius of the blur

numPasses - number of Box Blurs to perform to approximate a single Gaussian Blur

Method Detail

run

public Dataset run(Dataset dataSet)

Performs a Gaussian blur on the input.

Specified by:

run in interface DatasetOperation

Overrides:

run in class BoxBlur

Parameters:

dataSet - Dataset to blur

Returns:

blurred result, or null if input was null.
