Our Dental Diagnostics Department has written an Image Analysis tool that is
%%%%%% cliped from http://ddsdx.uthscsa.edu/dig/itdesc.html
UTHSCSA ImageTool (IT) is a free image processing and analysis program for
Microsoft Windows 95ª or
Windows NTª. IT can acquire, display, edit, analyze, process, compress, save
and print gray scale and color
images. IT can read and write over 22 common file formats including BMP, PCX,
TIF, GIF and JPEG. Image
analysis functions include dimensional (distance, angle, perimeter, area) and
gray scale measurements (point,
line and area histogram with statistics). ImageTool supports standard image
processing functions such as
contrast manipulation, sharpening, smoothing, edge detection, median filtering
and spatial convolutions with
user-defined convolution masks. IT also has built-in macro capabilities that
allow the user to record repetitive
tasks and playback saved macros to automate image analysis.
ImageTool was designed with an open architecture that provides extensiblity via
a variety of plug-ins. Support
for image acquisition using either Adobe Photoshop plug-ins or Twain scanners
is built-in. Custom analysis and
processing plug-ins can be developed using the software development kit (SDK)
provided (with source code).
This approach makes it possible to solve almost any data acquisition or
analysis problem with IT.
ImageTool provides for geometric transformations such as rotate, flip vertical,
flip horizontal and magnification
up to four levels. All analysis and processing functions are available at any
magnification factor. The program is
a multiple document interface (MDI) application supporting any number of
windows (images) simultaneously.
Spatial calibration is available to indicate real world dimensional
measurements such as millimeters, microns,
feet, miles, etc. for linear and area. Density or gray scale calibration can be
done relative to radiation or optical
density (OD) standards.
Future versions of IT will provides for image annotation with text, arrows,
rectangle, ellipses and polygon.
Multiple levels of undo are provided.
ImageTool is in beta release 1.0, we would appreciate any bug reports and
suggestions to improve IT as a tool
for imaging research. Bugs will be fixed and improvement made as time permits.
ImageTool was written using Borland's C++ version 4.5 and the source code for
the executable is available free
of charge. IT was developed in the Department of Dental Diagnostic Science at
The University of Texas Health
Science Center, San Antonio, Texas. The program was developed by C. Donald
Wilcox, S. Brent Dove, W.
Doss McDavid and David B. Greer.
As the old saying goes:
"You need IT, You ought to have IT,
So go ahead and FTP IT
ImageTool is available via anonymous FTP at
You will need to download Part 1 and Part 2. If you have already downloaded
Part 2 of either ImageTool or
Image Quiz you do not need to download it again. As both programs use the same
