Fiji is an image processing package. It can be described as a distribution of ImageJ (and ImageJ2) together with Java, Java3D and a lot of plugins organized into a coherent menu structure. Fiji compares to ImageJ as Ubuntu compares to Linux.

The main focus of Fiji is to assist research in life sciences.

For users, Fiji is easy to install and has an automatic update function, bundles a lot of plugins and offers comprehensive documentation.

For developers, Fiji is an open source project hosted in a Git version control repository, with access to the source code of all internals, libraries and plugins, and eases the development and scripting of plugins.

As announced in this mail, we join the legions of construction workers digging up the streets during the second half of July 2013 (i.e. we also use the slow summer month to break things in order to make them better), incorporating extensive changes to reconcile Fiji with ImageJ2. The packages below reflect Fiji as of July 15th, 2013 and are offered here just in case the continuous build (or an updated version) above broke a formerly working operation that is desperately needed, like, right now.
Life-Line version 32-bit Windows (32-bit) OS X1 Linux (32-bit) N/A All platforms
(no JREs)
64-bit Windows (64-bit) Linux (64-bit)
