What is ImageJ?




ImageJ is a software that can display, edit, analyze, process, save, and print images. It can read and write many formats, including TIFF, GIF, JPEG, BMP, DICOM, FITS, and raw. It can also handle stacks, or series of images that share a single window. It supports standard image processing functions such as contrast manipulation, sharpening, smoothing, edge detection, and median filtering. It can also perform geometric transformations such as scaling, rotation, and flips. Moreover, it can do measurements of area, mean, standard deviation, min and max of selection or entire image. It can also calculate histograms and line profile plots.


Features of ImageJ




Some of the features of ImageJ are:


  • It is platform-independent. It runs on Windows, Mac OS X, Linux, and any other system that has a Java runtime environment.



  • It is multithreaded. It can take advantage of multiple processors to speed up operations.



  • It is extensible. It has a built-in macro language that can automate tasks and add new features. It also supports plugins that can extend its functionality.



  • It is open source. It is freely available for download and modification.



Derivatives and variants of ImageJ




ImageJ has many derivatives and variants that are based on its source code or use its framework. Some of them are:


  • ImageJ2. It is a complete rewrite of ImageJ that aims to provide a more modern user interface, a more powerful plugin system, and better integration with other tools.



  • Fiji. It is a distribution of ImageJ that includes many plugins for image analysis, especially in life sciences.



  • Bio-Formats. It is a plugin that enables ImageJ to read and write over 150 file formats from various microscopy software.



  • CellProfiler. It is a software that uses ImageJ to perform high-throughput image analysis for cell biology.

For example, you can move it to Applications/ImageJ.
