ImageJ is a free, public domain software with the purpose of processing and analyzing scientific images. Initially developed in 1997 at the National Insititutes of Health in the United States by a developer named Wayne Rasband, it has been under continuous development ever since. Many iterations and variants of the software exist and it can serve a myriad of functions.

For the purposes of this course, we will be using the Fiji edition which is available as a free download for both Windows and macOS users. Fiji is specifically meant for biological image analysis, which we will be doing to track coral growth on one of our artificial reef projects. The software is simple and user-friendly, but highly useful for tracking the growth of coral colonies.

In this course, you will learn:

  • Why ImageJ is a valuable tool for coral reef monitoring and research.
  • How to download and install the software on your device.
  • How to take ideal photographs for analysis on ImageJ.
  • How to take accurate measurements of coral colonies using the software.
  • How to analyze these measurements in Microsoft Excel to track growth.

There will be quiz at the end of each lesson and a final examination to test your ImageJ knowledge.
