man imagej (1): A Java image processing program inspired by NIH Image.

SYNTAX

imagej [option] <filename>
imagej [-i image] [-b|-m] [arg1 ... argN]

DESCRIPTION

Imagej is a Java-based image processing program developed at the National Institutes of Health. ImageJ was designed with an open architecture that provides extensibility via Java plugins and recordable macros. Custom acquisition, analysis and processing plugins can be developed using ImageJ's built-in editor and a Java compiler. User-written plugins make it possible to solve many image processing and analysis problems, from 3-dimensional live-cell imaging,
to radiological image processing, multiple imaging system data comparisons to automated hematology systems. ImageJ's plugin architecture and built in development environment has made it a popular platform for teaching image processing.

ImageJ can be run as an online applet, a downloadable application, or on any computer with a Java 1.1 or later virtual machine.
