Field Details

localMaxRadius

public int localMaxRadius

Lines in transform space must be a local max in a region with this radius. Try 5;

minCounts

public int minCounts

Minimum number of counts/votes inside the transformed image. Try 5.

minDistanceFromOrigin

public int minDistanceFromOrigin

Lines which are this close to the origin of the transformed image are ignored. Try 5.

maxLines

public int maxLines

Maximum number of lines to return. If ≤ 0 it will return them all.

mergeAngle

public double mergeAngle

If two lines have a slope within this tolerance (radians) then they can be merged.

mergeDistance

public double mergeDistance

If two lines are within this distance of each other then they can be merged. units = pixels.

refineRadius

public int refineRadius

Radius of mean-shift refinement. Set to zero to turn off.

edgeThreshold

public ConfigEdgeThreshold edgeThreshold

How the gradient is thresholded
