ImageJ

    ImageJ is an open source Java image processing program inspired by NIH Image. It runs on any computer with a Java 1.8 or later virtual machine. Downloadable distributions are available for Windows, Mac OS X and Linux. ImageJ has a strong, established user base, with thousands of plugins and macros for performing a wide variety of tasks.

    Flavors

    There are a few different flavors of ImageJ with very similar names, and some confusion is inevitable. Below is a table which should help to clarify the purpose of each. For the historical context of these projects, see History below.

    Fiji

    Fiji contributors

    Fiji is Just ImageJ, with extras. It is a distribution of ImageJ with many plugins useful for scientific image analysis in fields such as life sciences. It is actively maintained, with updates released often.

    We recommend Fiji as the preferred version of ImageJ.

    ImageJ2
    ImageJDev

    ImageJ developers

    A new version of ImageJ targeting scientific multidimensional image data. It is a complete rewrite of ImageJ, but includes ImageJ1 with a compatibility layer, so that old-style plugins and macros can run the same as always. ImageJ2 provides several significant new features, such as an automatic updater, and improved scripting capabilities.

    ImageJ1

    Rasband

    A stable version of ImageJ which has been in development since 1997. It has a strong, established user base, with thousands of plugins and macros for performing a wide variety of tasks.

    ImageJA

    ImageJ developers

    ImageJA is a project that provides a clean Git history of ImageJ1, with a proper 'pom.xml' file so that it can be used with Maven without hassles.

    It is what ImageJ2's legacy support uses at its core.

    MBF ImageJ

    Tony Collins

    The MBF "ImageJ for Microscopy" bundle (formerly WCIF ImageJ) is a collection of plugins and macros, collated and organized by the MacBiophotonics facility.

    It went hand in hand with a comprehensive manual describing how to use the bundle with light microscopy image data. It was a great resource by microscopists, for microscopists. Unfortunately, the manual went offline in late 2012. In response, the software team at LOCI created the Cookbook user guide and update site, which includes most of the same plugins.

    ImageJX

    Grant Harris

    ImageJX was created as a means to discuss and explore improvements to ImageJ. There was an ImageJX mailing list as well as an ImageJX software prototype.

    The ImageJX software prototype was a proof of concept—an attempt to reorganize ImageJ's internals to make it more flexible. The prototype demonstrated this flexibility by recasting the program in Swing. The ImageJX project formed the basis of an application to NIH for funding, which is what launched the ImageJ2 project (see above).

    NIH Image

    Rasband

    NIH Image is a public domain image processing and analysis program for the Macintosh. It is the direct predecessor of ImageJ, and is no longer under active development (though see ImageSXM below).

    Superceded by ImageJ

    History

    The first imaging program that Rasband developed, starting in the late 70s, was called simply “Image”. It was written in Pascal, ran on PDP-11 minicomputers and ran in only 64KB of memory! Rasband started work on the second, NIH Image, in 1987 when the Mac II became available. Rasband was a Mac enthusiast, and the Mac II had card slots just like the PDP-11. Rasband started work on ImageJ in 1997, when Java was becoming popular. Rasband was intrigued by the idea of creating a version of NIH Image that would “run anywhere”, including as an applet in Web browsers.
