public class SoLocalStatisticsProcessing
extends SoImageVizEngine

SoLocalStatisticsProcessing engine SoLocalStatisticsProcessing image filter computes statistics on a sliding window.

The SoLocalStatisticsProcessing filter computes for each voxel of an image the value of a selected statistical operator on a predefined neighborhood. It creates a result image where output pixel values are only function of the corresponding pixel values in the input image and its neighborhood of a given size. These output values are extracted from local histograms which are arrays representing the number of pixels per value in the neighborhood. In the equations of each statistical operator description, corresponds to the probability to have a pixel with value (i.e., the number of pixels of value divided by the total number of pixels in the neighborhood).

Available statistical operators are:

• MEAN
• VARIANCE
• SKEWNESS
• KURTOSIS
• VARIATION
• CONTRAST
• ENERGY
• ENTROPY

computeMode

public final SoSFEnum<SoImageVizEngine.ComputeModes> computeMode

Select the compute Mode (2D or 3D or AUTO) . Default is MODE_AUTO

statisticalOperator

public final SoSFEnum<SoLocalStatisticsProcessing.StatisticalOperators> statisticalOperator

Select the first order measure to compute. . Default is MEAN

inImage

public final SoSFImageDataAdapter inImage

The input image. Default value is NULL. Supported types include: grayscale binary label color image.

kernelSize

public final SoSFInt32 kernelSize

Specifies the size of the kernel. The value of kernelSize is actually the 'half' kernel size. For example, kernelSize = 1 applies a 3x3(x3) pixel kernel in 2D(3D) when kernelShape is CUBE. Default value is 3.

kernelShape

public final SoSFEnum<SoLocalStatisticsProcessing.KernelShapes> kernelShape

Shape of the neighborhood. . Default is BALL

outImage

public final SoImageVizEngineOutput<SoSFImageDataAdapter,SoImageDataAdapter> outImage

The output image. Default value is NULL. Supported types include: grayscale binary label color image.
