For 3D (multi-slices) segmentation please use BalloonForce3DFilter The balloon force is vertical 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. <a href="classitk_1_1BalloonForceFilter.html#_details">More...</a><br></td></tr> <tr><td class="memItemLeft" nowrap align="right" valign="top">class </td><td class="memItemRight" valign="bottom"><a class="el" href="classDeformableMesh3D.html">DeformableMesh3D</a></td></tr> <tr><td class="mdescLeft"> </td><td class="mdescRight">The DeformableMesh3DFilter is used to deform a mesh (deformable model) under a potential force in 2D or 3D.
