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. | |

The OIV.ImageViz.Engines.EdgeDetection.Gradient.SoRadialGradientCenteredProcessing2d engine performs a projected gradient computing the directional vector.
For an introduction, see:
section OIV.ImageViz.Engines.EdgeDetection
section OIV.ImageViz.Engines.ImageFiltering
In the continuous 2-D case, for a given pixel and knowing the gradient and , the projected gradient of an image is defined along the unitary vector , as :
The OIV.ImageViz.Engines.EdgeDetection.Gradient.SoRadialGradientCenteredProcessing2d performs a projected gradient computing the directional vector from a single given center. For all pixel in the image, is the center.
It is a common way to get the recursive gradient in X and Y directions for input image and , using a spread of 60.
The projected resulting gradient image is the Normal Gradient. Simultaneously, the tangential gradient could be computed with the option GRADIENT_NORMAL_TANGENTIAL of OIV.ImageViz.Engines.EdgeDetection.Gradient.SoRadialGradientCenteredProcessing2d.ProjectionModes
