Detailed Description

template<class TInputMesh, class TOutputMesh>
class itk::BalloonForce3DFilter< TInputMesh, TOutputMesh >

BalloonForce3DFilter is a simplified form of the 3D deformable model. There are 2 forces applied on the surface of model. The balloon force and the gradient force. (1) The balloon force is a 2D force. In each slice, the balloon force is oriented along the normal direction of the model. (2) The gradient force is derived from boundary points locations in the original data. At boundary positions, the magnitude of the gradient is large and the gradient force, proportional to the gradient magnitude, will attract the model to these boundary locations. The combination of the two forces will drive the model nodes towards the boundary positions and stop them as they reach a boundary position (i.e high gradient position) The model motion is driven by the following equation:: d' + Kd = f_{int} + f_{ext} The model nodes positions are updated using the following iterative scheme: d_{n+1} = d_{n} + timestep * d' Input parameters are: (1) An original volume (2) A Deformable mesh (it can be derived from ShpereSource) (3) A potential map. This is a binary volume with object and background labelled differently (equivalent to a mask). This volume can be derived from GibbsPriorFilter or any other segmentation method.

A gradient volume is derived from a GaussainRecursiveFilter applied to the original data. This filter first applies a smoothing Gaussian filter to the volume and then computes the gradient in 2D for each slice.

In order to speed up the deformation process, this method initially deforms the model with only the balloon force (BalloonForceFilter method) so that the model expands inside the object binary mask. When the nodes on the model get close to the object mask boundary, the gradient force is turned on (GradientFit method) to refine the the model nodes position using the gradient information in the original volume. The BalloonForce3DFilter treats the 3D segmentation as series of 2D slices.
