Overview

The conversion between physical points and indices is not consistent in all places in the toolkit.

The following cases must be considered

  • Interpolators
  • Registration
  • Transforms
  • DICOM
  • Conversion between ITK and VTK
  • Backwards compatibility

Motivation

Review of Current Status

Interpolators

Interpolators are used in the Registration Framework and in the Resampling filters.
