<p>An educational system called GeoSim is being developed at Virginia Tech; its purpose is
to simulate processes related to several geographical subjects. The software consists of six
different modules; one of these modules is designed to simulate a field trip for orienteering
and position finding. This module uses a database of captured images to pan and zoom
from one location to another. However, the original images have overlapping areas which
does not allow simulating a continuous panoramic view. To fix this problem a cropping
tool was designed and implemented with Intel DVI ActionMedia boards to support the
orienteering module of project GeoSim. The tool allows cropping of overlapped areas in
the images. In addition, the tool allows the user to minimize differences in intensity and
colors between neighboring images. The cropping, color, and intensity values obtained from
manipulating images are saved in an ASCII file where they can be read and used in the
orienteering module. The images used are captured and stored on the hard disk from a
videodisc, with 512x480 resolution and 16 bits per pixel DVI compressed format.</p> / Master of Science
