Properties
  NameDescription
Public propertyautoMode

If this parameter is set to true the number of branches is computed automatically (the parameter OIV.ImageViz.Engines.ImageSegmentation.ComputationalGeometry.SoCenterLineApproximation3d.newBranchSensibility controls the adding of new branches) otherwise branches are added until OIV.ImageViz.Engines.ImageSegmentation.ComputationalGeometry.SoCenterLineApproximation3d.numberOfBranches connections is reached.

Public propertydistanceMapSmoothing

This parameter controls the smoothing of the distance map which is computed internally to make the tree centered.

Public propertyinLabelImage

Input label image.

Public propertyIsDisposable
ISafeDisposable interface implementation.
(Inherited from SoDisposable.)
Public propertynewBranchSensibility

This parameter controls the adding of a new branch in the tree in automatic mode.

Public propertynumberOfBranches

Number of branches iteratively added to the reconstructed centerline tree.

Public propertyoutBinaryImage

Output centerline.

Public propertyoutLineSet

Output line set.

Public propertysmoothingIteration

Number of smoothing iteration of the output line set (post processing).

Public propertyUserData
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.)
Top
Events
  NameDescription
Public eventOnBegin

Event raised when the processing begins.

(Inherited from SoImageVizEngine.)
Public eventOnEnd

Event raised when processing ends and the result is available.

(Inherited from SoImageVizEngine.)
Public eventOnProgress

Event raised while processing is running.

(Inherited from SoImageVizEngine.)

Remarks

The engine extracts the centerline of a label image. A centerline is a path with a tree topology that approximates the input shape. The extraction procedure enforces the path to be equidistant to its boundaries.

The engine searches for a graph with tree topology (without loops). If the object contains loops this algorithms will not fail, instead it will just ignore certain connectivity so that the tree topology of graph is preserved.

The engine searches iteratively for the longest branch that can be added to the tree.

Notice: This engine requires to preliminarily load the whole input data set into memory to be computed. As a consequence the input data set will be automatically loaded before the execution of this engine, ignoring the maximum memory parameter of the OIV.ImageViz.SbImageDataAdapterHelper.GetAppropriateAdapter(System.String, System.UInt64) function or OIV.ImageViz.Nodes.Images.SoFileDataAdapter classIf the input data set cannot fit in memory, this engine will fail during its computation.
