   Software Description

FREEDIUS is a portable, open-source toolkit for geospatial and image understanding research and development. FREEDIUS represents and manipulates images from various sources (including video) and has tools for sensor modeling, geospatial and cartesian coordinate systems and transformations, and geolocated 3D cultural features. Core libraries for FREEDIUS are written in C and C++ and are available as shared objects on Linux, Solaris, Irix, Windows, and (provisionally) Mac OS X. The FREEDIUS GUI subsystems are written in a combination of Lisp and C, and use Tcl/Tk and GTK as two alternatives for user interfaces and image display. Core display functions use OpenGL or SDL. FREEDIUS also has an extensive Video Understanding subsystem that handles DV and AVI formats, the SRI Small Vision System, and webcam video sources. The core FREEDIUS system is available from SRI at no charge under the Mozilla Public License.

   Associated Projects
SHAKEN

A Knowledge Entry System for Subject Matter Experts
The goal of SHAKEN project is to enable subject matter experts , without any assistance from AI technologists, to assemble the models of processes and mechanisms so that questions about them can be answered by declarative inference and simulation.

FREEDIUS

Open Source Three-Dimensional Image Understanding System
FREEDIUS is a portable, open-source image understanding workbench. It is the successor to the 3DIUS/CME system.

LAW

The Link Analysis Workbench
The goal of this project is to develop the Link Analysis Workbench (LAW), a Web-accessible tool where analysts and machines collaboratively perform link analysis by defining hierarchical and temporal patterns, that include uncertain and qualitative elements, and by defining search strategies for pattern application, through a graphical user interface that supports direct graphical browsing and editing of patterns, search strategies, and summaries and details of resulting matches.
