Overview

This is a module for the Insight Toolkit (ITK) that provides a generic interpolator for label images to interpolate each label with an ordinary image interpolator, and return the label with the highest value. This is the idea used by the itk::LabelImageGaussianInterpolateImageFunction interpolator. Unfortunately, this class is currently limited to Gaussian interpolation. Using generic programming, the proposed interpolator extends this idea to any image interpolator. Combined with linear interpolation, this results in similar or better accuracy and much improved computation speeds on a test image.

Installation

Since ITK 4.10.0, this module is available in the ITK source tree as a Remote module. To enable it, set:

Module_GenericLabelInterpolator:BOOL=ON

in ITK’s CMake build configuration.
