Summary

0008346: itkWarpImageFilter must have similar API to itkResampleImageFilter

Description

I’ve been doing some code refactorings to make sure that whenenver an itkResampleImageFilter is used that Origin/Spacing/Direction/Size/StartIndex are all set. While looking at the code, it occurred to me that the itkWarpImageFilter should also follow the same semantics as the ResampleImageFilter and provide a very similar interface.

In particular, the itkWarpImageFilter does not currently allow you to set the OutputStartIndex, and it also does not contain a member function called SetOutputParametersFromImage.

itkWarpImageFilter only works properly when output image has same physical space as output image.

Steps To Reproduce

Additional Information

A conversation with Luis Ibanez and Jim Miller resulted in consensus that the following actions should be taken:

1) Add SetSize and SetOutputStartIndex and SetOutputParametersFromImage member functions
2) Determine if outputImage and DeformationFeild have same physical characterisitics (i.e start index, size, spacing, origin, and direction)
a) If YES: use current algorithm
b) If NO: need to use trilinear interpolation of the deformation field at the physical coordinates of the voxels in the outputImage.
