Method Summary

protected void	cleanFragments() Clean up fragments - mostly sorting out links between peaks.
private void	clearIntArray(int[] array) Doesn't really zero the array but sets all elements to -1 so that we know they don't contain a valid index to any other peak.
protected boolean	closeRegion(ConnectedRegion region, int nJoinedEnd) Finish off a region if no more bits are to be added to it.
void	createFragments() Split the mother region up into fragments, breaking at every branch and join
int	fragmentRegion(ConnectedRegion connectedRegion) Fragment a connected region
ConnectedRegion	getFragment(int fragment) Get a specific fragment
int	getNumFragments() Get the number of fragments
boolean	isDiscardSmallOnes()
protected boolean	matchPeak(int[] peak1, int[] peak2, int connectType) Match to peaks - return true if they merge into one another.
protected void	sayFragment(int iFrag, ConnectedRegion region) Dump information on a single fragment ot screen.
protected void	sayFragments() Dump information to screen.
void	setDiscardSmallOnes(boolean discardSmallOnes) Set by teh RejoinFragments superclass so that all fragments are kept

FragmentingFragmenter

public FragmentingFragmenter(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 DiscardingFragmenter

Parameters:

connectedRegion - region to fragment

Returns:

number of fragments.

createFragments

public void createFragments()

Split the mother region up into fragments, breaking at every branch and join

closeRegion

protected boolean closeRegion(ConnectedRegion region,
                              int nJoinedEnd)

Finish off a region if no more bits are to be added to it.

Parameters:

region - region to close

nJoinedEnd - number of other bits coming out of this point

Returns:

true if the region is big enough to be worth keeping.

matchPeak

protected boolean matchPeak(int[] peak1,
                            int[] peak2,
                            int connectType)

Match to peaks - return true if they merge into one another.

Parameters:

peak1 - first peak

peak2 - second peak

connectType - connect 4 or connect 8

Returns:

true if they touch according to 4 / 8 rule

clearIntArray

private void clearIntArray(int[] array)

Doesn't really zero the array but sets all elements to -1 so that we know they don't contain a valid index to any other peak.

Parameters:

array -

zeroIintArray

private void zeroIintArray(int[] array)

Set all array elements to zero

Parameters:

array -

cleanFragments

protected void cleanFragments()

Clean up fragments - mostly sorting out links between peaks.

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 DiscardingFragmenter

Parameters:

fragment - fragment number (0 to getNumFragments);

Returns:

the ith fragment

getNumFragments

public int getNumFragments()

Description copied from interface: RegionFragmenter

Get the number of fragments

Specified by:

getNumFragments in interface RegionFragmenter
