ENGG/CSCI 8840: Advanced Image Analysis and Visualization

ANNOUNCEMENTS

Course will be offered when demand is large enough. If you are interested in this course, please let me know.

SUMMARY

Gain in-depth understanding, knowledge, and the ability to apply, cutting-edge methods to process and quantitatively analyze images. This class covers special and advanced topics of modern image analysis including wavelets, adaptive filters, active contours, and fractals. An important aspect is the design of unsupervised image analysis chains.
Prerequisites: ENGG 4620/6620 or instructor's consent.

Class schedule Fall 2017:
TBD

CONTENTS

INTRODUCTION

In ENGG4620, we examined how medical images are generated using CT, MRI, ultrasound, and other techniques. Since these modalities rely on computerized data processing, fundamental image processing steps were introduced.

What happens with those images? All too often, the radiologist hits the PRINT button, exposes a film and pops it into his light box for viewing. But the computer can do more!

The computer can improve the images by eliminating noise, amplifying contrast or accentuating features to be analyzed (enhancement).
The computer can separate features from background (segmentation).
The computer can take objective measurements of features, thus aiding the radiologist in his diagnosts (quantification)
The computer can superimpose or merge images from different modalities (registration)
The computer can reduce the data size for improved storage (compression)
And the computer can display image data in various ways (visualization).

Medical image analysis, however, is a complex task, calling for complex algorithms. With ever increasing computer power, very sophisticated algorithms have been introduced in recent years. In this class, we will cover some of those advanced algorithms.

The goal of this class is to give you knowledge and skills as follows:

  1. Knowledge of contemporary image processing and analysis algorithms
  2. An understanding how to design an image analysis chain
  3. Programming skills that allow you to implement your own algorithms

BOOKS

Recommended textbook for this class is:

M.A. Haidekker: Advanced Biomedical Image Analysis. Wiley 2011, ISBN 9780470624586.

You may also opt for any of these alternative textbooks:

Computer Imaging: Digital Image Analysis and Processing by Scott E Umbaugh (Taylor & Francis)

Medical Image Analysis by Atam P. Dhawan (IEEE Press)

COMPUTER LAB

Computers with the needed software (Crystal Image, ImageJ, OpenDX) are located in Room 314. You may need start the virtual Linux environment.

Alternatively, you may obtain the DVD that accompanies the textbook. This is a live DVD that allows you to run the software without modifying your hard drive.

GRADING

The grade will be based on the exam-style project, the homeworks, and the student lecture. You will receive score points based on the fill-the-bucket principle, i.e. for each homework assignment and for each test, you accrue score points. Your final grade will be determined from the score you achieved relative to the maximum score achievable. Typically, you receive a maximum of 15 points per homework, 100 points for the exam, and 100 points for the presentation, resulting in a maximum score of around 300 points.

We use a fixed grading system. There will be no adjustment based on the overall class performance. The following table shows the percentage of your score you need to reach for a specific grade:

GradeMinimum percentage GradeMinimum percentage GradeMinimum percentage
A+96% A93% A-90%
B+85% B80% B-75%
C+70% C65% C-60%
D+50% D45%   
To get a passing grade, you will have to achieve an overall score of at least 45%.
