Our software LaboImage (public domain, general purpose image analysis,
see doc below) includes a comprehensive 1D gel analysis program. This
program is based on work I performed at the NIH in 1982-1985, but has
been rewritten for Sun, then for Motif/X11.
We have not had the resources to run LaboImage on PC/DOS, but since it
is now based on Motif/X11, it is feasible.

Thank you for your interest in LaboImage!
Labo Image is a window based software for image processing and analysis. It
contains a comprehensive set of operators as well as general utilities. It
is designed to be open-ended; new modules can easily be added. The software,
written in C, is now based on X11 / OSF Motif. The current version has been
developped and tested on a Sun SPARC station, with X11r4 and Motif 1.1.
LaboImage has been extensively used by students as well as researchers from
various domains: computer science (image analysis), medicine, biology, physics.
It is distributed free of charge (source code).
Version 4.0, 1st December 1992:
- hosts: Sun SPARC station;
- OS: 4.1.1;
- window system: X11r4 / Motif 1.1;
- language: C;
- approx. code size: source 2.5MB (80'000 lines), executable 2.5MB;
- documentation: interactive help (english)
Means of distributions
LaboImage source code is available by anonymous ftp at:
1) ftp.ads.com, login name anonymous, in pub/VISION-LIST-ARCHIVE/SHAREWARE.
2) peipa.essex.ac.uk, login name anonymous, in ipa/proc-src.

- no responsibility is assumed;
- not to be used for profit making purposes;
- bugs will usually be corrected since we use the software intensively ;
- modifications should be communicated to us, with (normally) allowance
Athough LaboImage has undergone many upgrades and suffered in the hands of
many users, the current version is certainly not bug free. For the time being,
we require NO prepayment, return postage or anything.
We may however change this policy in the future, and ask for nominal fees to
cover material expenditures. HOWEVER, if you are satisfied with the product,
why not send us some "souvenir" (post card, drink, etc.)) from your country...??!!
Labo Image is an interactive software, whose interface is menu, mouse and
window based. Its main features are:
- input-output: LaboImage format file, SUN raster file; postscript;
- display: mono, RGB, dithering, color table editor;
- preprocessing: filters (median, high pass, low pass: hamming, gauss, etc),
background subtraction, histogram equalization;
- processing: thresholding, Fourier transforms, edge extractions: various
operators, ridge-riding, zero-crossing; segmentation into regions,
binary and gray tone mathematical morphology;
- measures: histograms, image statistics, power, region outlining,
- auxiliary: conversions, arithmetic & logical operations, noise addition,
image generation, magnification, convolution/correlation with
masks, image; padding;
- elementary interactive operations: region outlining, statistics and
histogram computation, etc.;
- special tools:
- modify image at pixel level interactively,
- one-dimensional gel analysis,
- expert system for image segmentation (not implemented in LaboImage 4.0);
- macros definitions, save and replay (not implemented in LaboImage 4.0);
- on line documentation.
Own format: descriptor file + data file (binary, byte, int, float, complex;
mono or RGB). Supports also Sun raster format. Conversions to various other
- iconic (pixel-based), with each image having its own parameter list;
- vectors (histograms, look-up tables);
Miscellaneous remarks (answers to commonly asked questions)
- FILE FORMAT: we decided to go for: 1) a machine independant format; 2) a
simple, data (ie. signal) oriented format. At the beginning of the
development (summer 1987), we were not aware of any image format used by
the whole community. There seems now to be some progress on the matter
(TIFF, etc.), but they are still not that widely used in the community.
Also, due to development priorities we consider conversion routines a more
secondary issue as long as our format is simple.
In addition, the menu "ACQUISITION=>free byte format" is fairly versatile.
Also, the SUN raster images can now be read into LaboImage and likewise
images on system may be stored in SUN raster format.
However.. we would welcome any software contribution!
- 3D IMAGE PROCESSING: nothing special for such images.
- ON LINE HELP: available.
More than 10 people have so far participated in this project, and their
contribution is gratefully acknowledged.
