Detailed Description

SoMorphologicalGradientProcessing engine

The SoMorphologicalGradientProcessing engine emphasizes the edges of the objects using morphological operations.

For an introduction, see:

• section Morphology
• section Edge Detection
• Introduction to Gradient

This engine emphasizes the edges of the objects using morphological operations. Two modes allow to enhance edges inside (Internal) or outside (External) of particles.

The SoMorphologicalGradientProcessing engine: (each with label image in overlay):
1: gray input image, 2: internal morphological gradient and 3: external morphological gradient.

This engine uses SoErosionDiskProcessing2d or SoDilationDiskProcessing2d in 2D case and SoErosionBallProcessing3d or SoDilationBallProcessing3d in 3D case. Two additional parameters are also provided : Precision of the computation (Faster or Precise) and half-kernel size for morphological operation.

Member Data Documentation

SoSFEnum SoMorphologicalGradientProcessing::computeMode

Select the compute Mode (2D or 3D or AUTO) Use enum ComputeMode.

Default is MODE_AUTO

SoSFInt32 SoMorphologicalGradientProcessing::elementSize

The half size of the structuring element.

A structuring element always has an odd side length (3x3, 5x5, etc) which is defined by 2 * elementSize + 1. Default value is 3.

SoSFEnum SoMorphologicalGradientProcessing::gradientMode

Select the computation mode for morphological gradient.

Use enum GradientMode. Default is INTERNAL

SoSFImageDataAdapter SoMorphologicalGradientProcessing::inImage

The input image.

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

SoImageVizEngineOutput<SoSFImageDataAdapter,SoImageDataAdapter*> SoMorphologicalGradientProcessing::outImage

The output image.

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

SoSFEnum SoMorphologicalGradientProcessing::precisionMode

Select the precision for computation method.

Use enum PrecisionMode. Default is FASTER
