THE VICAR IMAGE PROCESSING SYSTEM
which stands for Video Image Communication And Retrieval, is a general
purpose image processing software system that has been developed since
1966 to digitally process multi-dimensional imaging data. VICAR was developed
primarily to process images from the Jet Propulsion Laboratory's unmanned
planetary spacecraft. It is now used for a variety of other applications
including biomedical image processing, cartography, earth resources, astronomy,
and geological exploration. It is not only used by JPL but by several
universities, NASA sites and other science/research institutions in the
United States and Europe.
The VICAR core is being released Open Source! Click here for details.
The system consists of the following major subsystems:
- I/O and Common Libraries
- MIPL Data Management System
- Realtime Processing
- Science Processing
- Science Visualization
- Systematic Processing
- Science Uplink
Delivery specific help for individual VICAR programs
can be found here.
VICAR has its own file format which contains information
about the structure and type of the data, as well as a history of the
processing that has been done to the image. This is described in a document
The VICAR file format.
The Image-Based Information System
(IBIS) was designed to be a comprehensive geographic information system
that performs operations on raster image,tabular, and graphics format
data, using the Video Image Communication And Retrieval (VICAR) image
The current generation of the VICAR software,
was ported from a VMS only implementation into a portable version.
The VICAR porting guide describes the changes that were made to VICAR
programs to work in the new environment.
The core of VICAR is being released Open Source. While that includes much of VICAR some portions have been removed. If you have a need for the full capability, licensed versions can be requested from
for preparing and installing VICAR can be found in the
VICAR Installation Guide by Larry Bolef. This guide covers what platforms
are supported, what vendor and third party software is recommended or
required, disk space requirements, and all about patches and updates to
