Field Summary

Fields

Modifier and Type	Field	Description
double	convexTest	If the contour between two corners is longer than this multiple of the distance between the two corners then it will be rejected as not convex.
double	cornerScorePenalty	Used to adjust the penalty for adding a new corner.
ConfigLength	extraConsider	How many corners past the max it will fit a polygon to.
int	maxNumberOfSideSamples	maximum number of points along a side it will sample when computing a score used to limit computational cost of large contours
ConfigLength	maxSideError	Maximum allowed error along a single side in Eclidean distance in pixels.
int	minimumSideLength	The minimum length of a side
int	refineIterations	Extra refinement that it does after the initial polyline has been found.
double	thresholdSideSplitScore	If the error forside is less than this it is considered a perfect fit and the side won't be split.

Field Details

minimumSideLength

public int minimumSideLength

The minimum length of a side

extraConsider

public ConfigLength extraConsider

How many corners past the max it will fit a polygon to. This enables it to recover from mistakes. Relative: Maximum number of sides.

cornerScorePenalty

public double cornerScorePenalty

Used to adjust the penalty for adding a new corner. Larger numbers will bias it towards shapes with fewer sides. For simple convex shapes 0.2 is a reasonable value. For complex concave shapes 0.025 seems to do better.

thresholdSideSplitScore

public double thresholdSideSplitScore

If the error forside is less than this it is considered a perfect fit and the side won't be split. Adjust this value to improve the speed. Try setting to zero if corners are precise enough.

maxNumberOfSideSamples

public int maxNumberOfSideSamples

maximum number of points along a side it will sample when computing a score used to limit computational cost of large contours

convexTest

public double convexTest

If the contour between two corners is longer than this multiple of the distance between the two corners then it will be rejected as not convex. larger values make the tolerance weaker and smaller values make it more strict. Setting it too small can make it reject convex shapes.

maxSideError

public ConfigLength maxSideError

Maximum allowed error along a single side in Eclidean distance in pixels. Relative to number of pixels in contour.

refineIterations

public int refineIterations

Extra refinement that it does after the initial polyline has been found. Set to a value above zero to use this feature.

setTo

public ConfigPolylineSplitMerge setTo(ConfigPolylineSplitMerge src)

checkValidity

public void checkValidity()

Description copied from interface: Configuration

Checks to see if the configuration is valid. If it is invalid, throw an exception explaining what is incorrect.

toString
