Overview

This course provides an overview of the fundamental topics in image processing. Lectures emphasize the basic theory and the course projects explore some current topics and emphasize algorithm development and implementation. Course outline and additional information distributed in class on 01/04/2011 (Course Outline)

Topics for Winter 2011

1.     Introduction: an overview of some of the preliminaries.

a.      Digital picture transforms, 2-D DFT.

b.     Random fields and statistical image models.

c.      Image representations: 2-D sampling theory, generalization to random fields, representation using orthonormal basis functions.

2.     Digital Image Transforms and Coding

a.      Overview of transform compression

b.     Various transforms: Karhunen-Loeve, Fourier, Cosine, Hadamard, Walsh,

c.      2-D Wavelet transforms

d.     JPEG and JPEG-2000.

3.     Image Restoration

a.      Inverse and Least-squares filtering

b.     Maximum-likelihood (ML) and Maximum a-posteriori (MAP) estimation

4.     Image Reconstruction from Projections

a.      Image Projections and the Fourier Slice Theorem

b.     Filtered back projection algorithm

c.      Iterative reconstruction techniques

5.     Selected Topics: these will cover the general areas of image segmentation and image registration. Papers and course projects will explore these topics in more detail.

Grading

30% for H/W, preparing critiques, paper presentations, and participation in discussions; 30% for the class project; 40% for the final. HWs are due in class on the due dates. Class projects should involve some kind of computer implementation. Individual projects strongly encouraged but groups of two ok if the project needs are justified

Text/References

There is no required text book for the class. Lecture notes will be posted (will try my best to post them before the lectures). However, not everything that is discussed in class will be in these notes. I will also handout additional reading materials during the quarter.

 

Important dates

Jan 13, 2011

Paper assignments, groups

January 25

Project proposals are due on or before this date. Include a brief summary of proposed work and any appropriate references. Proposals should be no longer than 2 pages and hard-copies only. I will return the proposals with my comments on February 1. You are strongly encouraged to meet with me and discuss your proposals before submitting it.

 

Feb 3: Paper Critiques Due Before Class (email the electronic version, PDF files only, that will be posted on the class web site).
