RandomJ

A Java Package for Image Randomization

Distributions

General Description

RandomJ is a package of ImageJ plugin classes for introducing randomness into images. This may be useful for testing the robustness of image processing algorithms. The plugins can handle up to five-dimensional (5D) gray-scale images.

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

Binomial	Exponential	Gamma
Gaussian	Poisson	Uniform

Download

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

> RandomJ_.jar (version 1.4.0)
> 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 1.42b. 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 RandomJ is not available.

Acknowledgments

RandomJ was developed at the Biomedical Imaging Group Rotterdam of the Erasmus MC - University Medical Center Rotterdam, in the Netherlands, when I was evaluating the robustness against noise of certain tracking techniques developed in our lab. The different random number generators are based largely on algorithms found in the literature. Nevertheless, writing a general purpose package such as RandomJ is not completely trivial. Therefore, if you publish results that are based on it, I expect you to acknowledge me. Thanks in advance.
