Detailed Description

template<class TInputMesh, class TOutputMesh>
class itk::DeformableSimplexMesh3DFilter< TInputMesh, TOutputMesh >

Three-dimensional deformable model for image segmentation.

DeformableSimplexMesh3DFilter is a discrete three-dimensional deformable model, which can be used to deform a 3-D SimplexMesh.

The mesh deformation is constrained by internal forces. The interal force can be scaled via SetAlpha (typical values are 0.01 < alpha < 0.3). The external force is derived from the image one wants to delineate. Therefore an image of type GradientImageType needs to be set by calling SetGradientImage(...). The external forces are scaled via SetBeta (typical values are 0.01 < beta < 1). One still needs to play around with these values.

To control the smoothness of the mesh a rigidity parameter can be adjusted. Low values (1 or 0) allow areas with high curvature. Higher values (around 7 or 8) will make the mesh smoother.

By setting the gamma parameter the regularity of the mesh is controlled. Low values (< 0.03) produce more regular mesh. Higher values ( 0.3 < gamma < 0.2) will allow to move the vertices to regions of higher curvature.

This approach for segmentation follows that of Delingette et al. (1997).

This filter currently assumes that the spacing of the input image is 1.

The user has to set the number of iterations for mesh evolution.
