The Video Image Communication and Retrieval (VICAR) Image Processing System, developed by the JPL Multimission Image Processing Laboratory, has been a standard tool for analyzing space-probe images since the 1960s. VMS versions through 8.0 are available. Yet now, the advent of powerful, inexpensive microcomputers has made possible "desktop" image processing. Here, a set of software that parallels VICAR routines, and expands upon them, is presented, written for the DOS operating system.
PC VICAR was written in Microsoft FORTRAN by Chris Barnet for use on a 386-based microcomputer. Other hardware requirements include a Wieland Systems Design PCIP100A board and a separate video monitor for use as a display device. A CD-ROM drive is a convenient way of accessing raw Voyager images in PDS format.
PC VICAR was developed at New Mexico State University. An upgraded version is being tested at the University of Northern Iowa (UNI). This version accepts images in a variety of formats including Voyager , HST , Galileo , and those used with ground-based detectors. The software is user-friendly, and extra effort has been made to make the Voyager image-processing tasks simple and easy to understand. At UNI, we propose to provide other observers with image navigation and measurements of features associated with the collision of comet Shoemaker-Levy and Jupiter in July, 1994.
Funding for this project was provided in part by the NASA/University Joint Venture (JOVE) Program.
