Detailed Description

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

BalloonForceFilter is used to apply balloon force and the potential force onto the 2D surface model embedded in a 3D space.

The balloon force is normal to the surface of the model. The potential force is given out by the estimated boundary points. These two will meet a balance at the boundary, thus the deformable model will fit to the boundary. Users should use deformable model as input using SetInput and also provide the filter with a potential image which will provide the estimated bounday. The image should be a binary image with object and background labelled differently. These image can be given by GibbsPriorFilter or any other segmentation filters. When the nodes on the model stopped at the estimated boundary, using the GradientFit method to fit the model using the gradient information in the original image.
