A prominent example of how ImageJ has been adopted by the community is Fiji (Fiji Is Just ImageJ) and ImageJ2. The goal of Fiji (see Fiji paper9 for a thorough review) was to design a complete installation identical on any platform and which was easy to download and unpack. ImageJ2 (http://developer.imagej.net), the next generation of ImageJ is an NIH-funded collaboration between several institutions, groups and individuals, including Rasband. The ImageJ2 collaboration hopes to create more extensibility, modularity and interoperability as well as extend ImageJ community resources. ImageJ2 retains the interface of ImageJ but adds new architecture to remove some of the current limitations of ImageJ, such as data types, image size and dimensions. In addition to Fiji and ImageJ2, several other variants and programs based on ImageJ are currently available (Table 1).
