Constructor Detail

Deltas

public Deltas()

Creates a new Deltas DataProcessor

Method Detail

getDeltaOrder

public int getDeltaOrder()

Gets the order of the first derivate of the input data

Returns:

The order of the Delta

setDeltaOrder

public void setDeltaOrder(int order)

Sets the order of the first derivate of the input data

Parameters:

order - The order of the Delta

getDeltaDeltaOrder

public int getDeltaDeltaOrder()

Gets the order of the second derivate of the input data

Returns:

The order of the Delta-Delta

setDeltaDeltaOrder

public void setDeltaDeltaOrder(int order)

Sets the order of the second derivate of the input data

Parameters:

order - The order of the Delta-Delta

process

public void process(Buffer in,
                    Buffer out)
             throws DataProcessorException

Processes the input Data. Input data is treated as multidimensional data and therefore all processed vectors MUST have the same length. The returned data contains first the processed multidimensional data, then the delta and finally the delta-delta, thus the dimension of the output data is 3 times larger than the input one.

Parameters:

in - Input Buffer

out - Output Buffer

Throws:

DataProcessorException

editBeanInfo

public void editBeanInfo(java.beans.BeanInfo info)

Overrides:

editBeanInfo in class AbstractDataProcessor

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Throws:

java.lang.Exception
