Field Detail

numberOfSides

public int[] numberOfSides

Number of sides in the polygon it's trying to detect

contour2Poly_mergeTolerance

public double contour2Poly_mergeTolerance

Two lines are merged together if their angle is <= to this number.

contour2Poly_iterations

public int contour2Poly_iterations

Number of split and merge iterations when converting contour into polygon

contour2Poly_splitDistanceFraction

public double contour2Poly_splitDistanceFraction

Number of pixels, as a fraction of contour length, to split a new line in SplitMergeLineFitLoop.

refineWithLines

public boolean refineWithLines

Subpixel refinement using lines. This assumes that the lines are straight so it works best when lens distortion has been removed.

refineWithCorners

public boolean refineWithCorners

Subpixel refinement using corners. Doesn't require straight lines so it is more tolerant of distortion. However not as much information is being used so the fit might not be as good under ideal situations.

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.

PolygonEdgeScore

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?

configRefineLines

public ConfigRefinePolygonLineToImage configRefineLines

Configuration for refining with lines. Ignored if not used.

configRefineCorners

public ConfigRefinePolygonCornersToImage configRefineCorners

Configuration for refining with corners. Ignored if not used.
