When using nearest-neighbour interpolation and mapping to a lower-resolution image, if the default oversampling strategy is used, this will result in averaging of sub-voxel samples and therefore output intensities that do include some degree of "interpolation" with respect to the input image. This change disables oversampling when using nearest-neighbour interpolation.

I'd add a warning or throw an exception if the oversample option is provided but no template is provided. Also, do we want to offer the oversample option for warps as well? Not sure if it makes much sense to change the oversampling factor of the reslice filter that is applied to the warp. |
