Advanced Techniques in
Visual Learning & Recognition

CMSC828I - Fall 2020 · Unive-remove-rsity of Maryland


A graduate-level course in computer vision, with an emphasis on high-level recognition tasks. We will read an eclectic mix of classic and contemporary papers on a wide-range of topics. The course structure will combine lectures, in-class discussions, assignments, and a course project. The goal of this course is to:

  1. Become knowledgeable about how a particular sub-topic evolved, the state-of-the-art, and the challenges that need to be addressed.
  2. Develop skills to critically read, analyze, and discuss a body of research.
  3. Learn to draw connections between different works and engage in productive discussions.


While there are no formal prerequisites for this course, familiarity with introductory courses in computer vision (CMSC426 or similar) and machine learning (CMSC422 or similar) is assumed. If you have not taken courses covering this material, consult with the instructor. Note that a basic knowledge of linear algebra, probability, and calculus is required.

Accommodations and Policies

Academic Integrity

Note that academic dishonesty includes not only cheating, fabrication, and plagiarism, but also includes helping other students commit acts of academic dishonesty by allowing them to obtain copies of your work. In short, all submitted work must be your own. Cases of academic dishonesty will be pursued to the fullest extent possible as stipulated by the Office of Student Conduct. It is very important for you to be aware of the consequences of cheating, fabrication, facilitation, and plagiarism. For more information on the Code of Academic Integrity or the Student Honor Council, please visit

Excused Absence and Academic Accommodations

Any student who needs to be excused for an absence from a single lecture, recitation, or lab due to a medically necessitated absence shall:

  1. Make a reasonable attempt to inform the instructor of his/her illness prior to the class.
  2. Upon returning to the class, present their instructor with a self-signed note attesting to the date of their illness. Each note must contain an acknowledgment by the student that the information provided is true and correct. Providing false information to University officials is prohibited under Part 9(i) of the Code of Student Conduct (V-1.00(B) University of Maryland Code of Student Conduct) and may result in disciplinary action.
  3. This self-documentation may not be used for the Major Scheduled Grading Events as defined below.

Any student who needs to be excused for a Major Scheduled Grading Event, must provide written documentation of the illness from the Health Center or from an outside health care provider. This documentation must verify dates of treatment and indicate the time frame that the student was unable to meet academic responsibilities. No diagnostic information shall be given. The Major Scheduled Grading Events for this course include midterm and final exam. For class presentations, the instructor will help the student swap their presentation slot with other students.

It is also the student's responsibility to inform the instructor of any intended absences from exams and class presentations for religious observances in advance. Notice should be provided as soon as possible, but no later than the Monday prior to the the midterm exam, the class presentation date, and the final exam.

Any student eligible for and requesting reasonable academic accommodations due to a disability is requested to provide a letter of accommodation from the Office of Disability Support Services within the first three weeks of the semester.
