Open Geospatial Fundamentals
ImageJ Plugins - Digital Image Processing
|
These plugins extend the
open source image processing software
ImageJ
with respect to fundamental applications in geoinformatics and surveying.
While ImageJ isn't Photoshop - and is not meant to be -, it's quite a capable program,
and thanks to a macro recording facility and a powerful Java API, it's much easier to extend.
Being in the public domain, it's also free, and bugs are generally fixed quickly.
The plugins below should integrate well under other distributions of ImageJ, like
Fiji, too.
Download and install the latest version
of ImageJ bundled with Java first
(if not yet done).
