In addition, it is possible to calculate area, distance and angles, create a density histogram, and model line profiles. The last feature is achieved through the fact that the application can divide the tasks into threads and execute them in parallel. The program supports stacks that can be combined in one window, and also works very fast on multi-core systems. ImageJ allows you to work with images in almost all modern formats: TIFF, PNG, JPEG, BMP, GIF and so on. The program has a possibility of three-dimensional visualization, automatic comparison in several modes and so on. The application allows you to perform a comprehensive analysis of images, as well as display technical information about it. It is written in Java and created by a team of developers from the National Institutes of Health. The Fiji distribution of ImageJ bundles both ImageJ 1.x and ImageJ2, including ImageJ2’s backwards compatibility layer to transparently convert between ImageJ 1.x and ImageJ2 data structures as needed.ImageJ is a free software program for image analysis and processing. The other main flavor of ImageJ, a redesign started in 2010, is known as ImageJ2, to differentiate it from the original ImageJ. You may also sometimes see it called “plain ImageJ” or “ImageJ1” or “IJ1” by the community, but these are only shorthands. This wiki refers to the original version of ImageJ as the original ImageJ or ImageJ 1.x in places where it is important to distinguish it from other flavors of ImageJ. Now there are many hundreds, probably thousands, of plugins written by members of a diverse community. ImageJ grew organically over time as Wayne Rasband continued to add features according to user requests.

It was initially developed in 1997 as a cross-platform version of NIH Image. It has always been, and continues to be, a project of Wayne Rasband, with the help of many contributors. The original ImageJ has been under continuous development since 1997.

ImageJ is public domain software for processing and analyzing scientific images, with many derivatives and variants, including ImageJ2, Fiji, and others.
