Jim (Java Image Manager) is a program for managing your personal images (photos, etc.). While Jim is really easy to use, its tagging technology is quite powerful. A plugin system makes it easy extensible with new technologies. It runs on several operating systems (including Windows, Linux and many more); all you need is a Java Runtime Environment.
ScenePainter is a program for creating comics by (re-)arranging prefabricated graphic elements, taken from a media library. It can also be used as a developer tool for programmers and artists that are building games using threering's nenya library. Currently, ScenePainter does not ship with resourcefiles of its own, but is able to extract graphics from the games "Puzzle Pirates" and "Bang Howdy" by three rings design, inc. These graphics however, are copyrigthed materials and require permission to be used (e.g. for creating fan art).
Imageprot splits a JPEG or PNG image into small sub-images and creates an HTML page that assembles them back into the complete, original image in a Web browser. You can use this tool to simply protect your images from the "Save Image As" action and browser cache exploring. There is an option to generate random sub-image names, so it is hard to build the original image without analysing HTML code. This program, for obvious reasons, does not protect from downloading your image via the screen capture functionality present in most modern operating systems.
Kabeja is a Java library for parsing CAD data (i.e. Autodesk's DXF format) and converting to SVG (dxf2svg). You can use Kabeja from the command line or embed it into your application. It includes a plain DXF2SVGViewer and integration into the Cocoon XML Web development framework and the Inkscape SVG editor.
SIOX4Java (Simple Interactive Object Extraction) is a Java SDK that provides a generic segmentation engine for extracting the foreground from still images with little user interaction. The underlying method (which has also been integrated into GIMP) is noise and motion blur robust and can easily be adapted for the segmentation of objects in videos. The SDK also contains an experimental feature called the "Detail Refinement Brush", which enables the removal of spill colors and manual refinement of highly detailed textures.
XELand generates night landscapes as stereo pairs for cross-eye viewing. Currently it uses two map generation methods (plus some variations). Generated height maps are seamless and can be saved as PNG images. The program requires only JDK 1.5 or above, and is very easy to use. To take full advantage of XEland you should learn cross-eye viewing.
