Computer Vision

Computer vision is the "inverse" of computer graphics. In Computer Graphics, you give the computer a model, and it draws the picture. If you enjoy video games or computer animated films, you are benefiting from computer graphics. In Computer Vision, you give the computer a picture, and it computes the model. This might mean creating 3-D textured model from an image, or putting a box around a person's face. This can mean finding points that match in two images, or automatically aligning the images based on the point correspondences.

Course Description: This class provides a survey of modern computer vision topics and a computer vision design experience. After a brief introduction to the array representation of images and classical low-level algorithms, this course lays the foundation for modern computer vision on the foundational concepts of camera geometry, feature extraction, and machine learning. Students will implement a modern computer vision algorithm in a series of structured labs, after which they will implement a computer vision algorithms in a project experience. This class is intended for students with a strong programming background. (prereq: Junior standing in SE or CE programs and MA-383 and MA-231) 2-2-32 lecture hours

Outcomes

On successful completion of this course, the student will:

  • Interpret gray-scale and color images encoded as Matlab arrays
  • Implement simple computer vision algorithms by operating on raw pixel values
  • Compute projections and back-projections using the pinhole camera model
  • Stitch panoramas using homographies and RANSAC
  • Interpret machine learning algorithms as partitions of multi-dimensional space
  • Implement features and describe their role in vision
  • Understand the value of real-world and synthetic testing for computer vision algorithms
  • Design and implement a computer vision algorithm

(These are the official outcomes for this class from the catalog.)

Class

While I don't mind if you have to skip a class, class attendence is essential so you can learn what material I expect you to know, what HW and quizzes there will be, etc.

In class, I expect you to focus completely on class material. Instead of checking your email or browsing facebook, participate in the class activities and take notes of what you are learning.

If it becomes necessary to consider dropping the class, I am happy to give you advice, but I want you to make the final decision (with the help of your academic advisor). So if you stop coming class, I will not drop you, but instead give you whatever grade you have at the end of the quarter, even if it is an F.

Labs

This quarter, labs will be in teams of one or two, as marked on the lab assignment.

Lab attendence is required.

Labs may be turned in electronically or on paper. See the lab checklist for when the lab is due and how it should be submitted. In every uploaded file, include your name, date, and the assignment name.

Untested code is buggy. I find that if your code doesn't compile or hardly runs, that there are many other errors in it. To get more than half credit for a lab, it should compile and run when I test it (or you demo it). If it does not compile & run, please fix the lab and submit it later, or drop a feature or two to get it running again (often the best option).

For every day that goes by beyond the original deadline, it gets much harder to catch up on a lab. As a result, after the deadline, you can receive partial credit for a lab, up to 10% off per day.

All assignments must be turned in by 4:30pm on Friday of Week 10 so that we can wrap things up and I can turn the grades in on time.

Please start early and ask me for help if you get stuck.

Learning Assessment

This quarter, we will use the following to measure your learning:

Lab projects 25%
Final project 15%
Quizzes 15%
Half Exam 1 10%
Half Exam 2 10%
Final Exam 25%
Total 100%

I sometimes make mistakes in tallying points. If you become aware of an error in grading, please send me an email, and I will fix it and reply by email.

If the error goes beyond tallying points, discussing things in person is a great way to start to resolve an issue. I may ask you to send me an email if I think the case you are asking about requires careful consideration.

Please maintain your own records of your grades and check them against whatever summaries I send to you.

Quizzes & Exams

Quizzes will be announced in class at least one day in advance. They will usually be on Lab day.

Because of the difficulty of preparing fair and accurate tests, you cannot retake a quiz or exam if you miss it or do worse than you hoped. I will drop your lowest quiz score, so one 0 should not be a problem. If you need to skip an exam or half-exam, you should schedule a make-up exam before the missed exam. I don't always give make-up exams, even if students ask in advance.

Grade Scale

I use the official MSOE grading scale:

≥93% ≥89% ≥85% ≥81% ≥77% ≥74% ≥70% <70%
A AB B BC C CD D F

In final grading, I may award a grade higher than the grade scale if I feel it is more accurate than what the "raw numbers" produce.

Integrity

Your integrity is your most valuable academic possession, significantly more valuable than passing a class or getting a high GPA.

Academic integrity is essentially truthfulness — ensuring that if it appears you have done or know something, you have.

It is possible to accidentally give the impression that work is yours. If something like this happens to you, please let me know as early as possible. It is better if you point it out than if I find it.

Be on the watch for violations of academic integrity, including:

  • Receiving code from another student not on your team, even by looking at it.
  • Giving code to another student not on your team, even by showing them.
  • Looking at another student's work during a quiz or exam.

Read MSOE's Policy on Student Integrity for more details.

When coding, you are encouraged to discuss strategies, but the implementations should be independent. Even discussing the details is not a good idea if it goes too far. If you want to show code, start up an independent program rather than showing an assignment — and use a different application than the assignment at hand to demonstrate the concept you wish to share.

Because of the importance of maintaining academic integrity, I will report apparent academic dishonesty to the Vice President of Academic Affairs. If this occurs, you will get a copy of the report.

Fine Print

1In rare cases, I may need to reschedule an office hour. I will, if at all possible, announce this in class a day or more in advance.
