The SoImageCurvatureProcessing3d engine computes local gray level 3D curvatures in image.
This engine computes for each voxel of an input image local texture curvature. Computed curvature(s) takes voxel size into account.
This engine computes local gray level 3D curvatures in image. Each voxel is then associated to two principal curvatures : and . The stands for maximal local curvature whereas stands for minimal curvature.

Two important indicators can be extracted from these values :
Gaussian curvature can be used to characterize local surface comportment :

Constructor.
The input image.
Default value is NULL. Supported types include: grayscale binary label image.
The binary image for the mask or empty (command looks for only inside).
This parameter is optional. Default value is NULL. Supported types include: binary image.
SoImageVizEngineOutput<SoSFImageDataAdapter,SoImageDataAdapter*> SoImageCurvatureProcessing3d::outRealImageMax |

Default value is NULL. Supported types include: grayscale color image.
SoImageVizEngineOutput<SoSFImageDataAdapter,SoImageDataAdapter*> SoImageCurvatureProcessing3d::outRealImageMin |
The minimal curvature output image (floating values).
Default value is NULL. Supported types include: grayscale color image.
The standard deviation for Gaussian filter.
Default value is 4.0f.
