TransformJ

A Java Package for Geometrical Image Transformation

Clown

General Description

TransformJ is a package of ImageJ plugin classes for geometrical image transformation and manipulation, using simple as well as more complex and accurate interpolation techniques. The plugins can handle up to five-dimensional (5D) images.

A brief description of each of the plugins of the package as in the Panel is provided under the following links:

Download

The plugin package can be installed by downloading the following two files to the plugins folder of ImageJ:

> TransformJ_.jar (version 2.7.1)
> imagescience.jar (version 2.3.0)

By downloading any of the above, you indicate your agreement with the copyright notice and disclaimer below.

The first file contains the actual plugin classes while the latter is a library of support classes (you can download its API if you are interested in using its functionality also for other purposes).

This version requires at least Java 1.5 and ImageJ 1.41g. The program was tested and found to run properly on Windows XP (Service Pack 3). I haven't had the possibility yet to test it on other platforms so I don't guarantee anything there.

The source code of TransformJ is not available.

Acknowledgments

TransformJ was first developed during my stay at the Biomedical Imaging Group of the Swiss Federal Institute of Technology in Lausanne (EPFL), Switzerland, when I was financially supported by the Netherlands Organization for Scientific Research (NWO). The package is a completely revised, extended, and improved version of an earlier C++ library that I wrote during my stay as a PhD student at the Image Sciences Institute of Utrecht University, the Netherlands. If you publish results that are based on TransformJ, I expect you to acknowledge me.

The paper presents the results of a large-scale evaluation study of over 100 convolution-based interpolation techniques for geometrical transformation of medical image data, from which it was concluded that spline-based techniques yield the best cost-performance trade-off.
