(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. |
Name | Description | |
---|---|---|
computeMode | Select the compute Mode (2D or 3D or AUTO) . | |
inImage | The input image. | |
IsDisposable | ISafeDisposable interface implementation.
(Inherited from SoDisposable.) | |
neighborhood3d | In 3D configuration (see OIV.ImageViz.Engines.MathematicalMorphology.GeodesicTransformations.SoRegionalExtremaProcessing.computeMode), the neighborhood connectivity defines the connectivity considered for processing adjacent voxels. | |
outBinaryImage | The output binary image. | |
regionalOperator | Select the operator. | |
UserData |
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.) |
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. |
The OIV.ImageViz.Engines.MathematicalMorphology.GeodesicTransformations.SoRegionalExtremaProcessing engine computes the regional or relative fast maxima and minima in a grayscale image, , and displays the result in a binary image, . This algorithm is based on [1] and uses a recursive method combined with a geodesic propagation. To avoid getting too many regions in the output image, input should first be smoothed with a low-pass filter or with the dual numerical reconstruction algorithm.
Case Minima
This case of use computes the regional or relative minima in a grayscale image and creates a binary image containing these minima.
A regional minimum is a set of connected pixels such that:
Pixels belonging to have the same intensity .
Pixels connected to , but not belonging to (neighbors), have an intensity greater than .
Case Maxima
This engine computes the regional or relative maxima in a grayscale image and creates a binary image containing these maxima.
A regional maximum is a set of connected pixels such that:
Pixels belonging to have the same intensity .
Pixels connected to , but not belonging to (neighbors), have an intensity greater than .
