  whistlesAndMoans.DiscardingFragmenter

          whistlesAndMoans.RejoiningFragmenter

All Implemented Interfaces:

RegionFragmenter

public class RejoiningFragmenter
extends FragmentingFragmenter

Join fragmented shapes back together again. Probably not very efficient code since it goes through the list in fragments and if it joins two fragments together, it then removes one from the list, so the list gets progressively smaller.

Constructor Detail

RejoiningFragmenter

public RejoiningFragmenter(WhistleMoanControl whistleMoanControl)

Method Detail

fragmentRegion

public int fragmentRegion(ConnectedRegion connectedRegion)

Description copied from interface: RegionFragmenter

Fragment a connected region

Specified by:

fragmentRegion in interface RegionFragmenter

Overrides:

fragmentRegion in class FragmentingFragmenter

Parameters:

connectedRegion - region to fragment

Returns:

number of fragments.

checkDoubles

private void checkDoubles()

checkDuplicates

private void checkDuplicates()

crossCrosses

private void crossCrosses()

Find regions which are clearly crosses, then find all the bits to the left and the bits to the right, then join them together.

jumpCross

private boolean jumpCross(int crossIndex)

merge

private ConnectedRegion merge(int mergeIndex)

shortPenalty

private double shortPenalty(int fragLength)

calculate a penalty to penalise very short fragments by when deciding which are the best match during a merge of a split.

Parameters:

fragLength - fragment length

Returns:

penalty (to add to gradient difference)

branch

private boolean branch(int branchIndex)

mergeWhistles

private void mergeWhistles(ConnectedRegion r1,
                           ConnectedRegion r2)

matchPeak

private boolean matchPeak(SliceData sliceData1,
                          SliceData sliceData2,
                          int connectType)

removeShortFragments

private int removeShortFragments()

this will have called the super class fragmenter in a way which will have selected even the shortest fragments. Now need to get rid of those !

Returns:

number of remaining fragments.

getFragment

public ConnectedRegion getFragment(int fragment)

Description copied from interface: RegionFragmenter

Get a specific fragment

Specified by:

getFragment in interface RegionFragmenter

Overrides:

getFragment in class FragmentingFragmenter

Parameters:

fragment - fragment number (0 to getNumFragments);

Returns:

the ith fragment
