BSplineDeformableTransform () | |
~BSplineDeformableTransform () |
This class encapsulates a deformable transform of points from one N-dimensional one space to another N-dimensional space. The deformation field is modeled using B-splines. A deformation is defined on a sparse regular grid of control points and is varied by defining a deformation of each control point. The deformation at any point is obtained by using a B-spline interpolation kernel.
The deformation field grid is defined by a user specified GridRegion, GridSpacing and GridOrigin. Each grid/control point has associated with it N deformation coefficients , representing the N directional components of the deformation. Deformation outside the grid plus support region for the BSpline interpolation is assumed to be zero.
Additionally, the user can specified an addition bulk transform such that the transformed point is given by:
The parameters for this transform is N x N-D grid of spline coefficients. The user specifies the parameters as one flat array: each N-D grid is represented by an array in the same way an N-D image is represented in the buffer; the N arrays are then concatentated together on form a single array.
For efficiency, this transform does not make a copy of the parameters. It only keeps a pointer to the input parameters and assumes that the memory is managed by the caller.
The class is templated coordinate representation type (float or double), the space dimension and the spline order.

This method sets the parameters of the transform. For a BSpline deformation transform, the parameters are the BSpline coefficients on a sparse grid. The parameters are N number of N-D grid of coefficients. Each N-D grid is represented as a flat array of doubles (in the same configuration as an itk::Image). The N arrays are then concatenated to form one parameter array. For efficiency, this transform does not make a copy of the parameters. It only keeps a pointer to the input parameters. It assumes that the memory is managed by the caller. This method wraps each grid as itk::Image's using the user specified grid region, spacing and origin. NOTE: The grid region, spacing and origin must be set first. Reimplemented from itk::Transform< TScalarType, NDimensions, NDimensions >. |
