Scientific Visualization is the representation of
data graphcally as a means of gaining
understanding and insight into the data. People in
general, understand visual stimuli more easily than
complex amounts of data. An excellent place to
start learning Scientific Visualization is in the field
of Image Processing, since it involves algorithms
that help convert data into images. In today’s
technology-oriented world, the term ‘Image
Processing generally refers to the processing of a
two-dimensional data set using a computer. This
was the main reason that the initial research was
completed in the implementation of image
processing techtuques using a software called
Advanced Visual Systems Express (AVS Express).
There is a definite need to show how that would
benefit instruction as a teaching aid, and also how
it helps optimize the time taken to implement these
different techniques using this software. It also
increases user understandmg of these techniques.
It is possible to hlly implement many of the
different image processing techniques such as edge
extraction, gradient operators, convolution,
compression and extraction, as well as many others
in a relatively short time. In comparison to
previous attempts with other popular software such
as MATLAB, the time difference proved to be
immense. The main advantage of AVS software
is that it provides a visual programming
environment which allows the user to see the flow
of information of the lfferent algorithms as they
are being implemented. Since no time is spent
writing and correcting code, the understanding of
the image processing techniques becomes much
clearer in a shorter period of time, and thus in
depth study is possible. We have developed a
number of techmques and are in the process of
integrating AVS Express into the curriculum for
the Digital Image Processing (EE523) course at
Tennessee State University as a teaching and study
aid. We believe it will enhance the understanding
and implementation of image processing techniques
using Visualization methods.
