Constructor Detail

DifferenceOfGaussiansOperation

public DifferenceOfGaussiansOperation(BlurOperation first,
                                      BlurOperation second)

Creates a new DOGOperation with the specified blur operations.

Parameters:

first - first blur operation.

second - second blur operation.

DifferenceOfGaussiansOperation

public DifferenceOfGaussiansOperation(int firstRadius,
                                      int secondRadius)

Creates a new DOGOperation with two GaussianBlurOperations.

Parameters:

firstRadius - radius of first GaussianOperation

secondRadius - radius of second GaussianOperation

DifferenceOfGaussiansOperation

public DifferenceOfGaussiansOperation()

Creates a new DOGOperation with blur radii of 1 and 2.

Method Detail

run

public Dataset run(Dataset input)

Performs both blur operations on an input, and returns a new Dataset consisting of the difference between the two.

Specified by:

run in interface DatasetOperation

Parameters:

input - Dataset on which to operate

Returns:

resultant 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.

Specified by:

getSerializationVersion in interface ObjectMap

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.

Specified by:

getVersion in interface ObjectMap

Returns:

class version

getObjectMap

public java.util.Map<java.lang.String,java.lang.Object> getObjectMap()

Description copied from interface: ObjectMap

Creates a map of the important fields for the instance, suitable for serialization.

Specified by:

getObjectMap in interface ObjectMap

Returns:

"object map" of the instance

initCurrentVersion

public void initCurrentVersion(java.util.Map<java.lang.String,java.lang.Object> objectMap)

Description copied from interface: ObjectMap

Initializes an instance with a current-version object graph.

Specified by:

initCurrentVersion in interface ObjectMap

Parameters:

objectMap - object graph for initialization
