Course Description

The course addresses the problems of representation and reasoning for large amounts of visual data, including images and videos, medical imaging data, and their associated tags or text descriptions. We will introduce deep learning in the context of computer vision, and cover topics on visual recognition using deep models, such as image classification, object detection, human pose estimation, action recognition, 3D understanding, and medical image analysis. The course emphasizes the design of vision and learning algorithms and models, as well as their practical implementations.

Discussion Group

We will use Piazza. You are encouraged to post your questions on the discussion board so that others can learn from your questions.


Students are strongly encouraged to have knowledge of computer vision or machine learning (such as CS 540) or medical image analysis (such as BMI/CS 567). In addition, the following skills are necessary for this class:


Your final grade will be made up from Most of the assignments and projects are team based. We do not allow late homework assignments or projects. However, you have three "late days" for the whole course. That is to say, the first 24 hours after the due date and time counts as 1 day, up to 48 hours is two and 72 for the third late day.

These late days are intended to cover unexpected clustering of due dates, travel commitments, interviews, hackathons, etc. Don't ask for extensions to due dates because we are already giving you a pool of late days to manage yourself.

Homework Assignments

The course will consist of 4 homework assignments. All assignments except the first one are team based. Teams of 2-3 students are preferred. In your submission, please clearly identify the contribution of all the team members. Please note that members in the same group might not necessarily get the same grade.

Please post all of your questions on Piazza so that others may learn from your questions as well. Do not email the professor or TA directly with homework questions.

All homeworks are to be submitted by midnight on the due date. All files should be included in a zip file named (where X is the homework number) and uploaded to Canvas. Late submissions should be emailed to the TA (and carbon the instructor). Please attach the zip file in your email.

All starter code and assignments will be in Python with the use of various third party libraries. We will make an effort to support MacOS, Windows, and Linux. The course includes a quick Python tutorial (optional) and assumes you have enough familiarity with procedural and object-oriented programming languages to complete the projects.


The final project is research-oriented. It can be a pure computer vision project or an application of exisiting vision methods in the student's own research area. You are expected to implement one (or more) related research papers, or think of some interesting novel ideas and implement them using the techniques discussed in class. Students are encouraged to propose their own project topics. You should work on the project in groups of 2-3. In your submission, please clearly identify the contribution of both group members.

There will be four checkpoints for the final project: a project proposal, an intermediate milestone report, a final project report and a project presentation. The details are listed below.

Course Write-up

The course write-up will be a document that captures your reflection of the course work, e.g., what you have learned, what are the most interesting findings in the course. The write-up must be completed individually. It can be submited as a PDF file or a link to a webpage.

Academic Integrity

This course follows the University of Wisconsin-Madison Code of Academic Integrity. Unless specifically authorized by the instructor, all coursework is to be done by the student working alone. Violations of the rules will not be tolerated.

You are permitted and encouraged to discuss ideas with other students. However, you are expected to implement the core components of each assignment / project on your own / with your team. You should not view or edit anyone else's code. You should not post code to Piazza, except for starter code / helper code that isn't related to the core project.

The materials from this class rely significantly on slides prepared by other instructors, especially many slides are modified from those of Abhinav Gupta, Svetlana Lazebnik and Alexei A. Efros, who in turn uses materials from many people. Each slide set contains acknowledgments. Feel free to use these slides for academic or research purposes, but please maintain all acknowledgments.
