Most ImageJ-related practicals in this course only use core features, and so can be done using any of ImageJ, Fiji or ImageJ.JS. It remains my first choice for quick, common tasks with images. On my computer, it starts almost instantly. Its main disadvantage is that it’s a lot bigger: taking longer to start up and run update checks, and containing a lot of commands that I don’t always need.īy contrast, the original ImageJ is very small and lightweight. Therefore Fiji is my first choice for more extensive analysis tasks. ImageJ.JS doesn’t require any installation: just a modern web browser.Įverything ImageJ can do can also be accomplished in Fiji (because Fiji contains the full ImageJ inside it), but the converse is not true (because Fiji contains many extra bits) I always install both ImageJ and Fiji on any computer I will use regularly. It was put together and is maintained by the ImJoy team led by Wei Ouyang. It has a few extra features, but not as many as Fiji. ImageJ.JS is a web version of the original ImageJ, capable of running in a browser. It also has a powerful script editor that helps a lot when developing macros or scripts, an updater to help manage all the additions, and even a ‘Big Data Viewer’ for particularly huge images. Fiji #įiji, which stands for Fiji Is Just ImageJ, is a distribution of ImageJ that comes bundled with a plethora of plugins and extra features that are especially useful for life scientists. Including Java makes the download bigger, but makes the application self-contained and easy to run. You can download a platform-specific package that includes both ImageJ and Java for Windows, Mac or Linux. The core of the application is a tiny file ij.jar (~2.5 MB) that runs on Java. The ‘original’ download of ImageJ contains all the core functionality, but no extra user plugins. Three of the most important ones for our purposes are: 1. These sections are intended to help any interested reader develop a strong working knowledge of ImageJ itself, while simultaneously gaining a deeper understanding of image analysis in general. I personally have found ImageJ phenomenally useful throughout my career, to the extent that I am convinced that anyone working with biomedical images benefits if they know how to use it.Įven if you ultimately use other software for your analysis, or even write your own, the ability to quickly check things in ImageJ is extremely helpful. The source code is in the public domain, meaning that others can adapt it as needed.īut usually this isn’t necessary, because users can write (and share) custom macros, plugins or scripts to add new functionality – without changing ImageJ itself. ImageJ’s success is due not only to the features of the software itself, but to its openness and extensibility. It continues to be updated regularly and is by far the most discussed topic on the Scientific Community Image Forum – with more than 10,000 topics at the time of writing, and more added every day. ImageJ is open-source software for image analysis.Ĭreated by Wayne Rasband at the National Institutes of Health, ImageJ has become indispensable to the research community over more than 20 years. We begin with a brief introduction to what ImageJ is, how to get it, and how to navigate the interface to open and display images. This is the first section that takes the ideas described in the main chapter and shows how they relate to software: in this case ImageJ.
