SciJava Common is a shared library for SciJava software. It provides a plugin framework, with an extensible mechanism for service discovery, backed by its own annotation processor, so that plugins can be loaded dynamically. It is used by downstream projects in the SciJava ecosystem, such as ImageJ and SCIFIO.

This library contains ImageJ's core image data model, based on ImgLib2. It is the primary mechanism by which image data is managed internally by ImageJ2.
