Processing for Tsunamis

| Project description
and objectives:
|
|
Recently
a tsunami caused the
deaths of more than
200,000 people. This
proposed project is
an investigation into
how image processing
techniques can be used
to help with the problems
of tsunamis.
For
example, it may be possible
to predict the areas
of land which will have
the greatest initial
impact of a tsunami
before the impact takes
place. This may be achieved
by taking a satellite
image of the land, and
then applying appropriate
image processing techniques
to the image. The result
should be an image which
highlights the main
areas that will be affected
by the tsunami. An example
is shown below. |
| |
|
On
the left is an image of
a coastal area. On the
right is the image after
it has been processed.
It shows the areas of
ground that will have
the most impact if an
easterly moving tsunami
hits it. |
|
|
Image
processing techniques
can also be used to
provide a rough estimate
of the damage done by
a tsunami. For example,
the first and second
images show Aceh before
and after the tsunami.
By subtracting the second
image from the first
image, the third image
is created. |
 |
| |
In
this image, areas which
are not affected by
the tsunami are shown
as black. Areas where
a large difference has
been caused by the tsunami
are shown as other colours.
This kind of image would
be very useful for aid
agencies who can immediately
have a good idea of
the areas where the
greatest damage has
occurred, and send aid
accordingly. |

A
simple report or web page
which lists the techniques
which can be used to help
provide information about
tsunamis and their impact,
with example images. |
| Things students
will learn: |
| |
- How
images are represented
on a computer
-
How images can be
processed to extract
information
-
How to use image processing
software similar to
Photoshop

Experience
with handling images on
a computer is useful,
but not essential. |
