SyntaxThe SoLabelingProcessing type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SoLabelingProcessing | Constructor. |
Methods| Name | Description | |
|---|---|---|
| AbortEvaluate | Abort current processing as soon as possible. |
| Copy | Creates and returns an exact copy of the engine. |
| CopyFieldValues(SoFieldContainer) | Calls CopyFieldValues(fc, false). (Inherited from SoFieldContainer.) |
| CopyFieldValues(SoFieldContainer, Boolean) | Copies the contents of fc's fields into this object's fields. |
| Dispose |
Releases all resources used by SoDisposable.
(Inherited from SoDisposable.) |
| EnableNotify | Notification at this Field Container is enabled (if flag == true) or disabled (if flag == false). |
| Equals | (Inherited from Object.) |
| FieldsAreEqual | Returns true if this object's fields are exactly equal to fc's fields. |
| Get | Returns the values of the fields of this object in the Open Inventor ASCII file format in the given string. |
| GetAllFields | Returns a list of fields, including the eventIn's and eventOut's. |
| GetEventIn | Returns a the eventIn with the given name. |
| GetEventOut | Returns the eventOut with the given name. |
| GetField | Returns a the field of this object whose name is fieldName. |
| GetFieldName | Returns the name of the given field in the fieldName argument. |
| GetFields | Appends references to all of this object's fields to resultList, and returns the number of fields appended. |
| GetHashCode |
Overrides GetHashCode().
(Inherited from SoNetBase.) |
| GetName | Returns the name of an instance. |
| GetOutput | Returns a reference to the engine output with the given name. |
| GetOutputName | Returns (in outputName) the name of the engine output (output). |
| GetOutputs | Returns a list of outputs in this engine. |
| GetStringName | (Inherited from SoBase.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| HasDefaultValues | Returns true if all of the object's fields have their default values. |
| IsEvaluating | Returns true if the engine evaluation is in progress. |
| IsNotifyEnabled | Notification is the process of telling interested objects that this object has changed. |
| IsSynchronizable | Gets the ScaleViz synchronizable state of this object. |
| Set | Sets one or more fields in this object to the values specified in the given string, which should be a string in the Open Inventor file format. |
| SetName | (Inherited from SoBase.) |
| SetSynchronizable | Sets this to be a ScaleViz synchronizable object. |
| SetToDefaults | Sets all fields in this object to their default values. |
| StartEvaluate | Evaluate engine and dependencies in another thread without blocking the current one. |
| ToString |
Converts this SoBase structure to a human readable string.
(Inherited from SoBase.) |
| Touch | Marks an instance as modified, simulating a change to it. |
| WaitEvaluate | Wait for the end of engine evaluation. |
Properties| Name | Description | |
|---|---|---|
 | computeMode | Select the compute Mode (2D or 3D or AUTO) . |
| inObjectImage | The input binary or label image. |
| IsDisposable | ISafeDisposable interface implementation.
(Inherited from SoDisposable.) |
| neighborhood3d | In 3D configuration (see OIV.ImageViz.Engines.ImageSegmentation.Labeling.SoLabelingProcessing.m_computeMode), the neighborhood connectivity defines the connectivity considered for processing adjacent voxels. |
| outLabelImage | The output label image. |
| UserData |
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.) |
Events| Name | Description | |
|---|---|---|
 | OnBegin | Event raised when the processing begins. |
| OnEnd | Event raised when processing ends and the result is available. |
| OnProgress | Event raised while processing is running. |
RemarksThe OIV.ImageViz.Engines.ImageSegmentation.Labeling.SoLabelingProcessing engine labels objects of a binary image.
In this engine, the image is scanned from top to bottom and left to right. Each pixel of the same object takes the same value, and each object is assigned to a different value, starting from value 1. The assigned gray level depends on the location of the object in the image. The maximum gray level value gives the total number of objects in the original binary image. The algorithm works in three steps:
The first scan detects the start of each object.
The second scan gives the same gray level to all the pixels belonging to the same object.
The third optional scan checks that there is no hole in the numbers, i.e. that all objects have consecutive indices.
A label image may be 16 or 32 bits per pixel. By default it is 2 bytes per pixel, but if the number of labels exceeds 65,535 then the output image is automatically converted to 4 bytes and then can manage more than 2 billion labels.
