I’ve covered several scientific packages in this space that generate nice graphical representations of your data and work, but I’ve not gone in the other direction much. So in this article, I cover a popular image processing package called ImageJ. Specifically, I am looking at Fiji, an instance of ImageJ bundled with a set of plugins that are useful for scientific image processing.
The name Fiji is a recursive acronym, much like GNU. It stands for “Fiji Is Just ImageJ”. ImageJ is a useful tool for analyzing images in scientific research—for example, you may use it for classifying tree types in a landscape from aerial photography. ImageJ can do that type categorization. It’s built with a plugin architecture, and a very extensive collection of plugins is available to increase the available functionality.
The first step is to install ImageJ (or Fiji). Most distributions will have a package available for ImageJ. If you wish, you can install it that way and then install the individual plugins you need for your research.
