Field Summary

Fields

Modifier and Type	Field and Description
boolean	canTouchBorder If false then polygons which touch the image border are pruned
boolean	clockwise Will the found polygons be in clockwise order?
int	contour2Poly_iterations Number of split and merge iterations when converting contour into polygon
double	contour2Poly_minimumSideFraction The minimum allowed length of a side as a fraction of the total contour length
double	contour2Poly_splitFraction A line is split if a point along the contour between the two end points has a distance from the line which is greater than this fraction of the line's length
boolean	convex Does it require that the found polygons be convex?
int	maximumSides Maximum number of sides
double	minContourImageWidthFraction Specifies the minimum allowed contour length as a fraction of the input image's width.
double	minimumEdgeIntensity The minimum allowed edge intensity for a shape.
int	minimumSides Minimum number of sides
Configuration	refine Configuration for sub-pixel refinement of line.
double	splitPenalty Magic number used to penalize a polygon when a new corner is added

Field Detail

minimumSides

public int minimumSides

Minimum number of sides

maximumSides

public int maximumSides

Maximum number of sides

canTouchBorder

public boolean canTouchBorder

If false then polygons which touch the image border are pruned

contour2Poly_splitFraction

public double contour2Poly_splitFraction

A line is split if a point along the contour between the two end points has a distance from the line which is greater than this fraction of the line's length

contour2Poly_iterations

public int contour2Poly_iterations

Number of split and merge iterations when converting contour into polygon

contour2Poly_minimumSideFraction

public double contour2Poly_minimumSideFraction

The minimum allowed length of a side as a fraction of the total contour length

splitPenalty

public double splitPenalty

Magic number used to penalize a polygon when a new corner is added

MinimizeEnergyPrune

minimumEdgeIntensity

public double minimumEdgeIntensity

The minimum allowed edge intensity for a shape. Used to remove false positives generated by noise, which is especially common when using a local threshold during binarization.

Set to zero to disable.

PolygonEdgeIntensity

minContourImageWidthFraction

public double minContourImageWidthFraction

Specifies the minimum allowed contour length as a fraction of the input image's width. Smaller numbers mean smaller objects are allowed.

clockwise

public boolean clockwise

Will the found polygons be in clockwise order?

convex

public boolean convex

Does it require that the found polygons be convex?

refine

public Configuration refine

Configuration for sub-pixel refinement of line. If null then this step is skipped. Defaults to a line refinement algorithm.

ConfigRefinePolygonLineToImage, ConfigRefinePolygonCornersToImage

ConfigPolygonDetector

public ConfigPolygonDetector(int minimumSides,
                             int maximumSides)

Specifies the number of sides in the polygon and uses default settings for everything else

ConfigPolygonDetector

public ConfigPolygonDetector(boolean clockwise,
                             int minimumSides,
                             int maximumSides)
