Class Attendance Policy: Based on University Class Attendance Policy 1I9: It is the responsibility of students to ascertain the policies of instructors with regard to absence from class, and to make arrangements satisfactory to instructors with regard to missed course work. Failure to attend the first session of a course may result in the student’s place in class being assigned to another student.

Class Policies:  If you have a documented disability that requires academic accommodations, please go to Disability Support Services for coordination of your academic accommodations. DSS is located in the Student Success Center, Room 1270; you may contact them to make an appointment by calling (618) 650-3726 or sending an email to  Please visit the DSS website located online at:  for more information.

Present project to the class


ECE 439 Digital Image Processing - Semester Project

Semester Project: The project will consist of designing experiments, implementing algorithms, and analyzing the results for an image processing problem. You should work in groups of 2. The project will be selected by the students, subject to approval by the professor. The proposal, due week 10, will include: 1) topic, 2) algorithms to be explored, 3) number and type of images to be used, 4) method of evaluation of results

A paper will be written describing the project and discussing what was learned during the project. The final paper should be about 8 to 15 pages, typed and double-spaced; include images ! In the paper include an appendix containing program listing(s). The students will give a 5 minute presentation of their project in the lab to the class, the professor, and the lab instructor. Do NOT go over 5 minutes and do not have more than 10 PowerPoint slides! Also, an evaluation for each group member will be handed in or emailed with the report.

Ø  In addition to handing in a paper copy of the report, email me a soft copy of the Word file. Before you send me the file give it a meaningful name that includes your last name(s) and the project title.

Grading: The project is worth 25% of your term grade, broken down as follows:

  • Overall Project.. 15%
  • Paper................. 5%
  • Presentation........ 5%

Due Dates

Ø  Week 10:  Brief, 1 page max., project proposal

Ø  Week 16 (Finals week): Project paper due. Presentation//demo (finals week)

Suggested Project Process:

  • 1) Find an area of interest from the lab or from class; see Section 11.5.2 in textbook for project ideas.
  • 2) Design experiment(s) you wish to pursue
  • 3) Design algorithms/C function(s)/Matlab code to implement related to project
  • 4) Code and debug your function(s), or use CVIPtools
  • 5) Test your functions on some real images
  • 6) Process images/do the experiments
  • 7) Compare and contrast your results to other similar results from using CVIPtools functions, or research results in library from similar experiments - Analyze results using appropriate metrics, tabulate or plot, etc. Use the objective and subjective fidelity measures in Chapter 7 to compare images. Design your subjective measure experiments carefully as outlined in Chapter 7.
  • 8) Write report, include images
  • 9) Present/demo to the class

·  NOTE: If you do not have any specific images that you want to use, take a look at the image databases on the Internet, such as:


DIP Image Databases

Project Paper Format Outline

  • 1. Title page (project title, names, course number, date, etc.)
  • 2. Table of contents with page numbers for: different sections, figures, appendices, etc.
  • 3. Abstract - 1 page or less. Concise description of what is contained in the paper.
  • 4. Introduction/Project overview
  • 5. Body of paper. Broken down into sections as required for you project. For example: Background/theory, experimental methods, discussion and analysis of results, program descriptions, etc. Present results using graphs, images, etc.,
  • 6. Summary and conclusions. Summarize any results and draw conclusions as based on these results.
  • 7. Suggestions for future work. Include any ideas you have based on your work and conclusions about follow-up experiments and/or research.
  • 8. References. Be sure your references are complete. Avoid web sites as references – these come and go – find the source, which is usually a published paper.
  • 9. Appendices - related background information, program listings, etc.

General: reports should be typed, double spaced, pages numbered starting with abstract. Number of pages?- do what is necessary, but keep it concise, extra stuff can go in an appendix. DO NOT put in plastic folder, simply staple in upper left hand corner.
