EEGR6118 Applied Digital Image Processing (Fall 2008)

Instructor: Prof. T. Weldon

  • Course Outline

  • Course overview

    Overall, the course philosophy will be "to learn by doing."
    Students who have taken ECGR 4103/5103 Applied Computer Graphics will be best prepared for the course, otherwise students should have a good background in Fourier transforms or digital signal processing. We hope to set aside several weeks at the end of semester to allow students to independently pursue a topic of interest. You may choose Java/NetBeans/C++ or Mathcad to develop your project code to implement algorithms. This is a good opportunity to add programming language skills to your resume.

  • Some links of general interest:
  • For a quick tutorial on Java and Netbeans. see: NetBeans and Java tutorial
  • For more details on getting Java/Netbeans for your home PC, see: http://www.netbeans.org/
  • For a quick tutorial on Mathcad, see: Mathcad Introduction
  • For a quick tutorial on C++, see: Intro to C++, UNIX, and make
  • vecdemo: a simple C++ program example.

  • Projects

  • Images files for use in the course: Images

  • If you choose to program in Java/NetBeans/C++, you may wish to use ImgPro-jv41 as the starting point for your projects.
    ImgPro-jv41 is a Java/Netbeans-4.1 program for MSwindows that reads ".gif" and ".jpg" files, has a built-in logfft function, and writes ".png" output files.

  • Final Project
  • You may propose a special project only if you get approval to do so beforehand (this is not a guarantee that your proposal will be approved).
  • No segmentations are allowed using color images, all projects must use grayscale images, except for pre-approved special projects.
  • Your final project must be a complete image segmentation system that includes as a minimum:
  • An example image that is to be segmented
  • 3 features (i.e., Gabor, Laws, Sobel, etc.)
  • A vector classifier (Bayesian, nearest neighbor, etc.)
  • Either: 3 classes with morphological post-processing, or more than 3 classes. At least one class must be textured, unless you have some special project of equal complexity with prior approval.
  • Some ideas for projects:
  • See the Images page for ideas
  • See the images on the CD in the textbook
  • See the textbook
  • Segment the satellite image into rural, urban, ocean classes
  • Segment a brain scan into bone, brain, blood vessel
  • Photograph an outdoor scene and segment image into 4 classes: cars, people, buildings, other
  • Given a sequence of 2 or 3 photos at increments of 10 meters, estimate the ranges, and generate a 3D image (gamestudio mdl format file) of Woodward Hall
  • In a sequence of images of a moving car, identify the license plate, car, and letters

  • Proposal (10 percent of Final Project Grade)
    Due Nov. 10.
    4 pages maximum.
    Prepare a proposal for your final project.
    Your proposal must be in the following format:
  • Use this template: Proposal Template Page 1: cover page with proposal title and name
  • Page 2: Executive summary:
    describe your project in one half of a page or less, and on the bottom half of the page include a picure of an example image to be segmented, and a sketch of what you want the final segmented image to look like. Caption and label the image (i.e., Fig. 1. Image showing 3 classes to be segmented: trees, roads, and buildings.
  • Page 3: System Block diagram.
    At the top of the page provide a block diagram including separate blocks for each feature (Laws1, Laws2, Gabor 1, etc.), a block for the classifier, and a block for postprocesing. In the blocks, indicate the type of classifier/postprocessing. On the rest of the page, include the following headings and a paragraph describing each:
  • Features
  • Classifier Design
  • Post-processing
  • Page 4: Test data
    At the top of the page provide one or more images showing all of the classes that you want to segment. On the remainder of the page, describe the image classes (trees, roads, bone, muscle, chairs, etc), data source (where images came from, website, etc.), and segmentation problem (segment trees from roads). Include the following headings and a paragraph describing each:
  • Image classes
  • Data source
  • Segmentation problem

  • Design Review (20 percent of Final Project Grade)
    Due Nov. 24.
  • Use this template: Design Review Template
    You must demonstrate your feature images in class and turn in report. The features should clearly show that you can segment the image. It would be wise to show your classifier, too.

  • Final Presentation (20 percent of Final Project Grade)
    Due Last day of class (Dec 8).
    (20 percent of Final Project Grade)
    You must demonstrate your final project in class. Demonstrate that you can automatically segment the image.
    Final Presentation make-up: If your final presentation is not accepted, you have opportunity to do a second presentation, but with a 25% reduced grade. All make-up demonstrations will be conducted during the regularly scheduled final exam period, at which time all final reports are also due.
