Fiji represents an open-source software suite for image processing, built upon the ImageJ2 platform. It delivers a comprehensive distribution of ImageJ2, bundled with a wide array of plugins, featuring a unified menu layout and an integrated update mechanism. Fiji simplifies setup by providing thorough documentation, including in-depth algorithm explanations and tutorials, eliminating the need to source multiple components separately.
Aimed primarily at developers, Fiji offers support for version control, issue tracking, and swift prototyping through a script editor compatible with scripting languages such as BeanShell, Jython, JRuby, Clojure, Groovy, and JavaScript, along with just-in-time compilation for Java.
Plugins
The range of ImageJ plugins spans diverse applications and varying quality levels; some necessitate particular ImageJ versions, external libraries, or additional Java elements like the Java compiler or Java 3D. Fiji’s fundamental approach centers on streamlining the installation process for ImageJ, Java, Java 3D, plugins, and associated dependencies, which has contributed to its expanding and engaged user community.
Audience
Although initially created with neuroscientists in mind, Fiji’s user base has broadened to encompass researchers in fields such as cell biology, parasitology, genetics, life sciences, and materials science. Its core emphasis remains within the life sciences domain, providing a rich toolkit for scientific image analysis.
Within the life sciences sector, Fiji is particularly valued due to capabilities like the 3D Viewer that enables visualization of light microscopy data. It also supports sophisticated image processing functions including registration and segmentation to enhance analytical precision.
The Fiji module TrakEM2 has been successfully applied and refined for studying neuronal lineages in larval Drosophila brains.
Fiji’s significance in scientific data visualization has been recognized through coverage in high-profile journals such as Nature Methods.
Development
Fiji is entirely open source, with its codebase publicly accessible via a Git repository.
As an accepted organization in the 2009 Google Summer of Code, Fiji completed two projects that bolstered its development infrastructure.
Its scripting environment accommodates languages like JavaScript, Jython, JRuby, Clojure, and BeanShell, allowing developers to quickly prototype plugins before translating them into Java. A Google Summer of Code initiative introduced a script editor equipped with syntax highlighting and inline code execution capabilities.
This scripting environment is included in all Fiji distributions, enabling advanced users to embed scripts seamlessly into their workflows.
Progress is further fueled by regular hackathon events where computationally skilled life scientists collaborate to advance plugin development.
Script editor
The script editor within Fiji supports rapid creation and testing of scripts and ImageJ plugins, reinforcing Fiji’s role as a platform for innovating image processing algorithms and methods using ImageJ.
Supported platforms
Fiji is compatible with Windows, Linux, and Mac OS X (both Intel 32-bit and 64-bit architectures), with partial support available for MacOSX/PPC systems.
