• intTables

  private int[][] intTables

• numTables

  private int numTables

Constructor Detail

• LookupTableOperation

  public LookupTableOperation()

  Creates a LookupTableOperation for one lookup table.

• LookupTableOperation

  public LookupTableOperation(int numTables)

  Creates an object of this class, calling the super constructor with two null arguments and allocates space for the argument number of lookup tables.

  Parameters:

  numTables - number of tables to be used in this operation

Method Detail

• getNumTables

  public int getNumTables()

  Returns the number of tables in this operation.

  Returns:

  number of tables

• getTable

  public int[] getTable(int channelIndex)

  Returns one of the internal int lookup tables.

  Parameters:

  channelIndex - the zero-based index of the table to be returned; from 0 to getNumTables() - 1

  Returns:

  the channelIndex'th table

• prepareImages

  public void prepareImages()
                     throws MissingParameterException,
                            WrongParameterException

  Throws:

  MissingParameterException

  WrongParameterException

• process

  public void process()
               throws MissingParameterException,
                      WrongParameterException

  Description copied from class: Operation
  This method does the actual work of the operation. It must be called after all parameters have been given to the operation object.

  Overrides:

  process in class Operation

  Throws:

  MissingParameterException - if any mandatory parameter was not given to the operation

  WrongParameterException - if at least one of the input parameters was not initialized appropriately (values out of the valid interval, etc.)

• process

  private void process(IntegerImage in,
                       IntegerImage out)

• process

  private void process(IntegerImage in,
                       IntegerImage out,
                       int CHANNEL_INDEX,
                       int tableIndex,
                       int processedItems,
                       int TOTAL_ITEMS)

• setNumTables

  public void setNumTables(int numberOfTables)

  Resets the number of tables to be used in this operation to the argument and drops all actual table data initialized so far. After a call to this method, getTable(int) will return null as long as no new table data is provided via setTable(int, int[]) or setTables(int[]).

  Parameters:

  numberOfTables - the new number of tables for this operation, must be 1 or larger

  Throws:

  java.lang.IllegalArgumentException - if the number is zero or smaller

• setTable

  public void setTable(int channelIndex,
                       int[] tableData)

  Provides a new lookup table for one of the channels.

  Parameters:

  channelIndex - the index of the channel for which a table is provided; must be at least 0 and smaller than getNumTables()

  tableData - the actual table to be used for lookup

  Throws:

  java.lang.IllegalArgumentException - if the channel index is not in the valid interval (see above)

• setTables

  public void setTables(int[] tableData)

  Sets the tables for all channels to the argument table. Useful when the same table can be used for all channels.

  Parameters:

  tableData - the data that will be used as lookup table for all channels
