Image Processing Tutorial for Viking Images
NIH Image is a program originally developed by the National Institutes
of Health (NIH) for processing medical images, although we'll use it for
processing planetary images.
First time users click here to get
started with NIH Image.
The NIH Image
manual is also online as a reference guide.
This tutorial will help you to process your own Viking images,
particularly those found on the Mission to Mars: Digital Image Maps
(MDIMs) and Viking raw images CD-ROMs. These CD-ROMs are
available from NSSDC.
If you have enough memory on your computer (16 MB or more), you can run
NIH-Image as you read this tutorial. If not, it may be easier to print
out sections of this tutorial and keep them handy as you experiment with
- The alpha 5 version of NIH-Image for PCs running Microsoft Windows
95. Most Mac-Image functions, including acquiring Planetary Data System
Format (PDS) images, have not been implemented yet. You may want to check
the Image ftp site for more recent releases of
- IMDISP (A DOS-based image display program). Read the README file and
type HELP after starting the program for more information.
