Detailed Description

class itk::fem::FEMScatteredDataPointSetToImageFilter< TInputPointSet, TInputMesh, TOutputImage, TInputConfidencePointSet, TInputTensorPointSet >

Scattered data approximation to interpolation in the presence of outliers.

Given a 2- or 3-D scattered and noisy data, this filter is able to approximate the data while rejecting outliers, and then it advances toward interpolation.

This filter also takes the confidence and structrual information into account, if users can provide a scalar to represent the confidence and a tensor to represent the structural information for each feature point.

This filter requires a point set, of which each point is associated with a 2-D or 3-D displacement, as input, and outputs a deformation field. Two optional point sets are supported. Confidence point set: this point set defines the confidence associated with each point, which will make the solver behavior like a weighted Least Square Tensor point set: this point set defines a tensor associated with each point, such as a structural tensor.

The purpose of this filter is to facilitate the use of the FEMRobustSolver, which does the concrete work on finding the solution. See FEMRobustSolver for details.
