MARF is a general cross-platform framework with a collection of algorithms for audio (voice, speech, and sound) and natural language text analysis and recognition, along with sample applications (identification, NLP, etc.) of its use. MARF can run distributed over the network (CORBA, Java RMI, and Java XML-RPC Web Services) and may act as a library in applications or be used as a source for learning and extension.
FrAid (Fr[actal] Aid) is a programming language that is appropriate for mathematical computations, visualization, batch processing, and more. It features both a standalone application that provides a programming environment for the language and a system for integrating the language with Java. The Java interface allows mathematical equations and formulas to be used with Java code, making it easier to process numerical computations, symbolic computations, imaging, CAD, and more.
The JAVE (Java Audio Video Encoder) library is a Java wrapper on the ffmpeg project. Developers can take take advantage of JAVE to transcode audio and video files from one format to another. For example, you can transcode an AVI file to an MPEG one, you can separate and transcode audio and video tracks, and you can resize videos, changing their sizes and proportions. Many other formats, containers, and operations are supported by JAVE.
The Deimos Project is a 3D space combat simulator and modular game library collection. It includes a 3D modeler designed with a programmer's needs in mind. It allows you to construct 3D models by writing Java source code. All you need to design a model is a computer, some graph paper, and a pencil. The modeler's internals function as a simple OpenGL scene graph API, without preventing the use of low-level OpenGL commands. For storing settings and other hierarchically-representable data, the project provides a Hierarchy library that stores data atomically using XML. It also features a timing library, a game object container system, and many other features.
