Detailed Description

template<class TDisplacementField, class TOutputImage>
class itk::GridForwardWarpImageFilter< TDisplacementField, TOutputImage >

Warps a grid using an input deformation field.

GridForwardWarpImageFilter warps a grid with respect to a given deformation field.

A displacement field is represented as a image whose pixel type is some vector type with at least N elements, where N is the dimension of the input image. The vector type must support element access via operator [].

The output image is produced by forward mapping.

Each vector in the displacement field represent the distance between a geometric point in the input space and a point in the output space such that:

$p_{in} = p_{out} + d$

Typically the mapped position does not correspond to an integer pixel position in the output image. We round it.
