NIH-Image
Features
(comments from user Edwin van Spronsen <edwin@sara.nl>
- Both 68K and PPC versions available.
- Very good documentation in MsWord format.
- Live video on any AV Mac and support for several third party frame-grabber
cards.
- Great tools for measuring shapes, densities, particle counting and analysis,
etc.
These features were described in more detail in:
Biotechnology & Bioengineering (1992) vol. 39, p.343-350.
- Support for PhotoShop plug-ins.
- An easy to learn macro language for automating repetitive tasks. Over
the years,
many macros for a wide range of tasks have been contributed by users to
the above site.
For those who want to dig even deeper: the Pascal source code is also available.
- FFT (Fast Fourier Transform) and inverse FFT calculation and direct manipulation
of the power spectrum with PhotoShop-style filters and painting tools. If
you're familiar
with FFT's you'll be impressed by the speed on a PowerMac. It's also an
excellent way
of explaining these techniques to students.
On-line User-to-User Assistance
There's also a very active mailing list for users of this program, in
order to subscribe you'll have to send to LISTPROC@SOILS.UMN.EDU

Applications:
As a biologist I wanted to monitor dividing algae over a 72 hours period.
I wrote a
10-line macro that would read a video image every 30 seconds, skip every
image that didn't show any movement by comparing it to the previous one
and write the relevant images to disk, adding the date and the time of
day to the filename. It was a completely automated experiment.
Although originally developed for microscopists, it's easy to envisage
applications in surveillance, process monitoring, motion and shape
analysis, etc.
Specific Applications
NIH Image - It's not just for biologists!
NIH Image allows students use digital imaging technology the same way as
scientists do... as a tool for analyzing data. Kids can calculate the speed
and path of hurricanes from satellite images, create three-dimensional visualizations
of topography from contour maps, or analyze the trajectory of a basketball
free-throw to understand the force of gravity. In the hands of students,
NIH Image is an exciting tool for exploring digital images from scanners,
digital cameras and video, government CD-ROMs, and the Internet.
Given a digital image of anything too large, too small, too fast, or too
slow to examine or measure in real time, students can analyze the image
to learn more about its subject. Using NIH Image, students can set a scale
and measure lengths, areas, or angles of still and animated scenes. They
can change colors to emphasize items of interest or reveal hidden features
of an image.
Training in NIH-Image Educational Use
Teachers and students are using NIH Image as a learning tool on Macintoshes
across the nation. The Center for Image Processing in Education (CIPE) has
trained over 2500 educators to use NIH Image as a tool for teaching. CIPE
also distributes curriculum materials covering concepts in science, mathematics,
and technology through analysis of digital images.
CIPE is currently offering workshops for teachers plus curriculum products
on CD-ROM for specific science and math courses. Within the next few weeks,
they will be shipping an interactive tutorial on using NIH Image for teaching.
Stay tuned for a special offer to Evangelists!

CIPE's materials are developed at the University of Arizona with funding
from the National Science Foundation and the Annenberg/CPB Project.

Description:
- CampOS Math develops problem-solving skills for the classroom
Portland, OR- October 31, 1995- Pierian Spring Software announces
the new
release of CampOS Math, which develops problem-solving skills and builds
confidence in using mathematics. This discovery-based program encourages
students to investigate mathematical concepts and develop methods and
strategies for problem-solving in a 3D real-world environment. It allows
teachers to easily integrate the program into the classroom in a variety
of
ways such as a whole class discussion, cooperative learning groups,
laboratory settings, or individualized instruction.
In designing the CampOS Math program, the standards set by NCTM (National
Council of Teachers of Mathematics) for grades 5-8 were utilized to ensure
that the program would break the barriers of rote memorization of facts
and
algorithms. The program focuses on rich mathematical content against a
backdrop of historical artifacts and portraits of famous mathematicians.
Among the many topics covered in the program, it includes interactive
devices that help students with fractions, primes, percents, ratios, and
many more unique illustrations of mathematics.
Using the Digital Chisel, a multimedia authoring tool, teachers and
students can create supplementary projects, presentations, reports, and
tests that can be attached to any screen within the existing software.
Teachers can now build customized math lessons down to the smallest detail.
Pierian Spring Software is a Kodak and Apple Education Solutions Provider
whose mission is to help teachers teach and students learn.
