Constructor Detail

ConvolutionOperation

public ConvolutionOperation()

Creates a new ConvolutionOperation with the identity kernel.

ConvolutionOperation

public ConvolutionOperation(double[][] k)

Creates a new ConvolutionOperation with the specified kernel.

Parameters:

k - kernel to use

ConvolutionOperation

public ConvolutionOperation(Dataset kernel)

Creates a new ConvolutionOperation with the specified kernel.

Parameters:

kernel - kernel to use

Method Detail

getKernel

public double[][] getKernel()

Returns the convolution kernel.

Returns:

convolution kernel

getWidth

public int getWidth()

Returns the width of the kernel i.e. kernel.length.

Returns:

width of kernel

getHeight

public int getHeight()

Returns the height of the kernel i.e. kernel[0].length.

Returns:

height of kernel

run

public Dataset run(Dataset input)

Convolves a Dataset.

Specified by:

run in interface DatasetOperation

Parameters:

input - Dataset to convolve

Returns:

convolved Dataset

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
