Method Summary

Modifier and Type	Method and Description
protected boolean	mergeSegments() Merges lines together which have an acute angle less than the threshold.
boolean	process(java.util.List<georegression.struct.point.Point2D_I32> list) Approximates the input list with a set of line segments
protected int	selectSplitBetween(int indexStart, int indexEnd) Finds the point between indexStart and the end point which is the greater distance from the line (set up prior to calling).
protected void	splitPixels(int indexStart, int indexStop) Recursively splits pixels.
protected boolean	splitSegments() Splits a line in two if there is a paint that is too far away

Constructor Detail

SplitMergeLineFitSegment

public SplitMergeLineFitSegment(double splitFraction,
                                double minimumSplitFraction,
                                int maxIterations)

Method Detail

process

public boolean process(java.util.List<georegression.struct.point.Point2D_I32> list)

Description copied from class: SplitMergeLineFit

Approximates the input list with a set of line segments

Specified by:

process in class SplitMergeLineFit

Parameters:

list - Ordered list of connected points.

Returns:

true if it could fit a polygon to the points or false if not

splitPixels

protected void splitPixels(int indexStart,
                           int indexStop)

Recursively splits pixels. Used in the initial segmentation. Only split points between the two ends are added

splitSegments

protected boolean splitSegments()

Splits a line in two if there is a paint that is too far away

Returns:

true for change

selectSplitBetween

protected int selectSplitBetween(int indexStart,
                                 int indexEnd)

Finds the point between indexStart and the end point which is the greater distance from the line (set up prior to calling). Returns the index if the distance is less than tolerance, otherwise -1

mergeSegments

protected boolean mergeSegments()

Merges lines together which have an acute angle less than the threshold.

Returns:

true the list being changed
