If you want to learn how to use ImageJ and/or ImageJ2 (as opposed to write programs with ImageJ2), then visit ImageJ Tutorials.
This project contains example code for working with ImageJ2 and SciJava.
This repository is broken down into two main functional parts: Notebooks and Java.
The purpose of the notebooks is to give a "guided tour" for teaching ImageJ2.
The purpose of the java section of this repository is to give a collection of examples and howtos for different use cases.
