## Overview

Graduate advanced topics class offered in the Spring 2006 semester.
This subject qualifies as a Artificial Intelligence and Applications Engineering Concentration subject.
We will study various methods for turning computers into image forming devices.

In many fields, compute-intensive reconstruction methods produce
images from raw data that may be considered to be in a coded form.
Often the image construction involves inversion of
an operation that is simple in the forward direction.
Since computing is becoming cheaper and faster, replacing
optics, or electromagnetic apparatus, or electronics with
computing can be a driving force in some such image forming applications.

A basic understanding of image processing and/or
machine vision will be assumed.
Familiarity with concepts of linear systems, convolution,
and Fourier transforms will be handy.

There will be two lectures a week,
and I hope to encourage discussion and student participation.
There will be some papers to read, although in some of the
areas to be covered there isn't that much written yet.
There may be homework problems from time to time.
