boofcv.alg.shapes.polyline.splitmerge.SplitMergeLineFit

boofcv.alg.shapes.polyline.splitmerge.SplitMergeLineFitLoop

@Deprecated
public class SplitMergeLineFitLoop
extends SplitMergeLineFit

Deprecated.

Implementation of SplitMergeLineFit for looped lists of points. The beginning and end of the list are assumed to be connected. An additional check is done in the start to find two points which are far apart.

Method Summary

Modifier and Type	Method	Description
boolean	_process(List<Point2D_I32> contour)	Deprecated.
protected int	circularDistance(int start, int end)	Deprecated. Distance the two points are apart in clockwise direction
protected boolean	mergeSegments()	Deprecated. Merges lines together if the common corner is close to a common line
protected int	selectFarthest(List<Point2D_I32> contour)	Deprecated. Computes the distance between pairs of points which are separated by 1/2 the contour list.
protected int	selectSplitOffset(int indexStart, int length)	Deprecated. 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 length)	Deprecated. Recursively splits pixels between indexStart to indexStart+length.
protected boolean	splitSegments()	Deprecated. Splits a line in two if there is a point that is too far away

SplitMergeLineFitLoop

public SplitMergeLineFitLoop(double splitFraction,
 ConfigLength minimumSplit,
 int maxIterations)

Deprecated.

• SplitMergeLineFit(double, ConfigLength, int)

Method Details

_process

public boolean _process(List<Point2D_I32> contour)

Deprecated.

Specified by:

_process in class SplitMergeLineFit

splitPixels

protected void splitPixels(int indexStart,
 int length)

Deprecated.

Recursively splits pixels between indexStart to indexStart+length. A split happens if there is a pixel more than the desired distance away from the two end points. Results are placed into 'splits'

selectFarthest

protected int selectFarthest(List<Point2D_I32> contour)

Deprecated.

Computes the distance between pairs of points which are separated by 1/2 the contour list. The index of the first pixel in the pair with the greatest distance is returned

Returns:

Index of the first pixel which should be used to split the list. The other end is ret + N/2

mergeSegments

protected boolean mergeSegments()

Deprecated.

Merges lines together if the common corner is close to a common line

Returns:

true the list being changed

splitSegments

protected boolean splitSegments()

Deprecated.

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

Returns:

true for change

selectSplitOffset

protected int selectSplitOffset(int indexStart,
 int length)

Deprecated.

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 of the element with a distances greater than tolerance, otherwise -1

Returns:

Selected offset from start of the split. -1 if no split was selected

circularDistance

protected int circularDistance(int start,
 int end)

Deprecated.

Distance the two points are apart in clockwise direction
