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

Image Class

The image class considers that the location of a pixel is at the physical coordinates of the center of the pixel.
