I recently spotted a summary of image processing software
which was posted to several newsgroups before, I believe,
the sci.image.processing newsgroup was created.

Hopefully it will have some appeal to readers of this
newsgroup.

SUMMARY OF IMAGE PROCESSING SOFTWARE, PART 1 of 2

Part 1 contains information about applications for (1) Macintosh
computers, (2) PC computers, (3) GRASS, and (4) Khoros.

Part 2 contains information about other image processing 
packages for UNIX systems (5).
 

About two weeks ago, I posted the following query to several UseNet 
newsgroups and listserv mailing lists:

"I am interested in learning about what Image Processing software 
packages people are using for the analysis of multi-band data sets, 
such as Landsat Imagery. What are the major software packages in use? 
What are the capabilities of each package -- e.g. rectification, 
classification, PC and IHS transformations, filtering, contrast 
enhancement, overlays? Is the software designed specifically for 
remote-sensing images, medical images, or more generally for any kind 
of multi-band images? What are the hardware requirements? Any special 
requirements for display systems?"

"I am particularly interested in any software for Macintosh 
platforms, but would like to hear about packages that people are 
using on PCs and UNIX workstations as well. I am familiar with 
Terra-Mar's "MicroImage" software, and have heard of "ERDAS" but know 
nothing about it. I am also familiar with some single-band image 
processing software such as the excellent public-domain "NIH Image" 
program for the Macintosh."


Below is a summary of information that I have gathered so far.  I 
apologize for any mistakes or misquotes resulting from my butchering 
-- I mean my editing -- of the responses I received.  I welcome 
comments, corrections and further contributions to this list.

1 - Macintosh Software
--------------------------------------------------------------------

NIH Image 
This is an excellent image processing application that is 
in the public domain.  The application, documentation and source code 
are available for anonymous ftp from alw.nih.gov.  I've used NIH 
Image to analyze scanned photographs of rock outcrops, among other 
things.

From a summary by ritley@uimrl7.mrl.uiuc.edu: "You can get NIH Image
from
ALW.NIH.GOV (128.231.128.251) in the It has painting and manipulation
tools, a macro language, tools for measuring distances and angles, and
for
counting things. It can record sequences to be played back as a movie.
You
can invoke user-defined convolution matrix filters, such as Gaussian.
It
has a pretty powerful import capability, that lets you import raw data
in
tab-delimited ASCII, or as bytes or 2-byte quantities. The author uses
this
to read in MRI data from a proprietary system. It also does histograms
and
even 3-D plots. It is limited to 8-bits/pixel, though the 8 bits map
into a
color lookup table, as is standard on the Mac for 8-bit color. It runs
on
any Mac that has a color screen and a FPU (or you need a FPU emulator,
but
I imagine it is pretty slow)."

Frank Hoffman <hoffmann@URZDFN.KARTOGRAPHIE.TU-DRESDEN.DBP.DE> wrote: 
"We are using IMAGE from NIH (developed by Wayne Rasband) on a MAC 
machine. It works fine for manipulating not only the tomographic head 
examples but also for airphoto manipulating. I managed also a DEM 
example scanned from a "DEM-photo" with 0-255 discrete altitude 
values arranged in a TIFF-matrix. I have no idea if there is a 
possibility for multi-band images, students took the manual with 
them, so I cannot answer at this moment."

(NIH Image does not support mult-band images.)

---------------------------------------------------------------------
NCSA Image 
This is a similar program, but I didn't find it as useful 
as NIH Image.  NCSA provides a whole suite of public-domain 
visualization tools for the Macintosh, primarily aimed (I think) at 
researchers wanting to visualize results from numerical modelling 
calculations.  These applications, documentation, and source code are 
available for anonymous ftp from ftp.ncsa.uiuc.edu.  

Commercial versions of the NCSA programs have been developed by 
Spyglass.

Greg Radke <TNF70@isuevax.iastate.edu> wrote: "They make a series of 
products called Transform, View, Dicer, Format. Transforms allows 
data manipulation and charting configuration, while View only allows 
you to "view" and edit the "view characteristics" Dicer is allows you 
to slice through true 3-d data and see the contours, etc."

If you can get a hold of one of the old Macintosh Developer CDs, you 
might want to look at the Satellite Image Workshop program. It comes 
with a number of satellite pictures (raw data) and does all sorts of 
image enhancing on it. You'll need at least a Mac II with co-
processor; a 256 color display and a large harddisk. The program 
doesn't run under system 7.x.ATE1 V1

I have been getting up to speed on a program called RSVGA available 
from Eidetic Digital Image Ltd. in British Columbia.  Its for IBM 
pc's or clones, cheap (about $400) and does all the stuff Erdas does 
but is not as fast or as powerful, though I have had only limited 
experience with Erdas.  I have used RSVGA with 6 of 7 Landsat bands 
and it is a good starter program except for the obtuse manual.

super VGA cards.  Its a full blown remote sensed data processing 
system.. It is menu driven (character based screen), but is does not 
use a windowed user interface. Its is hardware protected with a 
dongle. Mbrian = micro Barrier reef Image Anaysis System. It was 
developed by CSIRO (Commonwealth Scientific & Industrial 
Organization) and is marketed/ supported by MPA Australia (51 Lusher 
Road, Croydon, Victoria tel + 61 3 724 4488     fax  +61 3 724 4455) 
Contact them for pricing .. there are educational and commercial 
prices, but be prepared to set aside $A10k for the first educational 
licence.  Subsequent ones come cheaper (they need to!) It has 
installed sites worldwide.  It is widely used here at ANU.

3 - GRASS 
--------------------------------------------------------------------

Several people mentioned the "public-domain" Geographic Resource 
Analysis Support System (GRASS) of the US Army Construction 
Engineering Research Lab (CERL). Many may think of GRASS as a 
Geographic Information System rather than an Image Processing 
package, although it is reported to have significant image processing 
capabilities.  I've pieced together the following information from 
some news announcements from Rob Knauerhase 
<rob@amber.cecer.army.mil> of CERL-OGI:

CERL's Office of Grass Integration (OGI) maintains an ftp server:

moon.cecer.army.mil (129.229.1.16)

Connections are only allowed during off- peak hours (weekends and 
weekdays before 8:00 A.M. and after 5:00 P.M. Central Standard time).  
Mail regarding this site should be addressed to ftp-
admin@moon.cecer.army.mil.

This location will be the new "canonical" source for GRASS software, 
as well as bug fixes, contributed sources, documentation, and other 
files. This FTP server also supports dynamic compression and 
uncompression and "tar" archiving of files.  A feature attraction of 
the server is John Parks' GRASS tutorial.  Because the manual is 
still in beta-test stage, John requests that people only acquire it 
if they are willing to review it and mail him comments/corrections.  
The OGI is not currently maintaining this document, so all 
correspondence about it should be directed to grassx@tang.uark.edu

Listserv mailing lists:

grassu-list@amber.cecer.army.mil (for GRASS users; application-level 
questions, support concerns, miscellaneous questions, etc)
Send subscribe commands to grassu-request@amber.cecer.army.mi.

grassp-list@amber.cecer.army.mil (for GRASS programmers; system-level 
questions and tips, tricks, and techniques of design and 
implementation of GRASS applications) 
Send subscribe commands to grassp-request@amber.cecer.army.mi.

Both lists are maintained by the Office of Grass Integration (subset 
of the Army Corps of Engineers Construction Engineering Research Lab 
in Champaign, IL). The OGI is providing the lists as a service to the 
community; while OGI and CERL employees will participate in the 
lists, we can make no claim as to content or veracity of messages 
that pass through the list.  If you have questions, problems, or 
comments, send E-mail to lists-owner@amber.cecer.army.mil and a human 
will respond.

4 - Khoros 
--------------------------------------------------------------------

Many people mentioned Khoros, a powerful and extensive image 
processing and visualization software development environment from 
the University of New Mexico. I've pieced together the following 
information from the various news announcements and FAQs that people 
sent me:

Khoros components include a visual programming language, code 
generators for extending the visual language and adding new 
application packages to the system, an interactive user interface 
editor, an interactive image display package, an extensive library of 
image processing, numerical analysis and signal processing routines, 
and 2D/3D plotting packages:

*  X Windows Applications:
Animate - Interactive Image Sequence Display Tool
Cantata - Extensible Visual Programming Language
Concert - A system for distributed X user interfaces (groupware)
Editimage - Interactive Image Display & Manipulation Program
Xprism2 and Xprism3 - Comprehensive 2D and 3D Plotting Packages
Viewimage - A basic interactive program for surface rendering
Warpimage - An interactive program for registering and warping images

*  Data Processing Algorithms:
Khoros contains over 260 programs, in the following categories: 
arithmetic, classification, color conversion, data conversion, file 
format conversion, feature extraction, frequency filtering, matrix 
algebra (LINPACK and EISPACK), spatial filtering, morphology 
filtering, geometric manipulation, histogram manipulation, 
statistics, signal generation, linear operations, segmentation, 
spectral estimation, sub-region, and transforms. Khoros supports the 
following file formats: TIFF, pbm, BIG, DEM, DLG, ELAS, FITS, MATLAB, 
Sun raster, TGA, and xbm.

*  User Interface Tools
Preview  - Graphical User Interface Display Tool
Composer - Interactive Graphical User Interface Editor
Conductor - Code Generation Tool for a Graphical User Interface
Ghostwriter - Code Generation Tool for a Command Line User Interface
Source Configuration & Management - Tools to install and maintain a 
distributed source tree.

To run Khoros, you must have a UNIX platform running the X11R3, 
X11R4, X11R5, or OpenWindows servers. The Khoros system consists of 
~450,000 lines of C code;  you will need a maximum of 120 Megabytes 
of storage for source, documentation and binaries.  To compile 
Khoros, the system requires X11R4 (patch levels 1-18) or X11R5 client 
software from MIT and an additional 50 Megabytes of storage.

The Khoros user community has ported Khoros to various other 
platforms such as the Convex, the Sequent, Data General Aviion, 
MacII, and 386/486 machines. At this time, these platforms are not 
directly supported by the Khoros Group.

Khoros is available via anonymous ftp at no charge (from 
pprg.eece.unm.edu, 129.24.24.10, in the /pub/khoros directory), or a 
tape and printed documentation can be ordered for $250.00.  

Support is provided via both a user's group mailing-list:  
khoros@chama.eece.unm.edu  (send subscription requests to khoros-
request@chama.eece.unm.edu); and a USENET Newsgroup:  comp.soft-
sys.khoros  

For more information, send e-mail to khoros-
request@chama.eece.unm.edu.  All communication to the Khoros group 
should be via e-mail.
