Constructor Detail

BoxBlur

public BoxBlur(int rank)

Creates a new BoxBlur of the specified rank (aka radius).

Parameters:

rank - radius of the blur operation

BoxBlur

public BoxBlur()

Creates a new BoxBlur of radius 5.

Method Detail

run

public Dataset run(Dataset dataSet)

Performs a fast 2D box blur by implementing a separate vertical and horizontal blur.

Parameters:

dataSet - Dataset to blur

Returns:

blurred Dataset, or null if input Dataset was null.

VBlur

public Dataset VBlur(Dataset dataSet)

Performs a vertical blur on the dataset. One component of the two-step fast Box Blur.

Parameters:

dataSet - Dataset to blur

Returns:

blurred Dataset, or null if input Dataset was null.

HBlur

public Dataset HBlur(Dataset dataSet)

Performs a horizontal blur on the dataset. One component of the two-step fast Box Blur.

Parameters:

dataSet - Dataset to blur

Returns:

blurred Dataset, or null if input was null.

getSerializationVersion

public long getSerializationVersion()

Description copied from interface: ObjectMap

Returns the current version of the serialization format. Increments when the serialization format changes, i.e. backwards compatibility is broken.

Returns:

serialization version

getVersion

public int getVersion()

Description copied from interface: ObjectMap

Returns the current class version. Class version increments when the class changes but doesn't necessarily break compatibility with serialization.

Returns:

class version
