Current information

Prof. Eisemann will no longer teach this course, for the moment. If you look for something similar, try "Bildbasierte Modellierung" by Prof. Magnor. Possibly, the two courses will be merged. Stay tuned.

The repeat exam takes place on February 20th, 2024 in G30. To register follow the instructions below.

Language

Since the course is also offered in the Master Data Science program, the language of the course is English.

Description

After successful completion of this module, students have a basic understanding of the development of complex computer vision applications. They are able to understand computer vision problems and to design and effectively implement suitable (AI-based) solutions.

Registration

To participate in the lecture and exercise, you can register on our website under "Teaching -> Course Enrollment" (direct link https://www.graphics.tu-bs.de/teaching/students ).

Studip is not used for this course.

Exercises

In the exercises, programming will be done in Python with OpenCV and PyTorch.

The exercise tasks will be uploaded Thursdays and discussed on the following Thursday in the exercise session.

The tasks of each exercise sheet must be completed in groups of three to five people and uploaded to the Git repository by Wednesday 23:59 at the latest. Don't forget to include names and matriculation numbers in the repository.

The practical tasks must be demonstrated in the exercise session. Working groups of up to five people are allowed, but everyone in the group must be able to answer any questions about the tasks and the code independently.

The frameworks and solutions have been tested on the computers in the CIP Pool. Unfortunately, we cannot guarantee direct support for other systems. A computer with Linux or Windows is required for completing the tasks. The functionality of the framework under Mac OS/X cannot be guaranteed. If you encounter any issues, please contact us via email at cvml@cg.cs.tu-bs.de.

Exam

The examination date can be found under Place and Time.
Any changes will be announced in the lecture and on this website in time.

  • Exam format: written exam (90 minutes)
  • Certificate acquisition by passing the exam (at least 50% of the points)
  • Requirement for module completion: at least 50% of the points achieved in the exercises.
  • Exam participation is recommended for every course of study!
  • Students must register with the examination office!

Repeat Exam

If you have failed the regular exam or wish to claim a free attempt, you have the opportunity to take the repeat exam.

If that would be your last chance (usually the third) to pass the course, then please continue reading the section "Supplementary Exam"!

In semesters where the course is taught this is simply the regular exam. So all you need to do is register for the regular exam.

In semesters, where the course is not taught, it usually takes place during the first lecture-free week. To register, please sign up for the exam regularly at the examination office and send a corresponding email requesting a repeat exam to sekretariat@cg.cs.tu-bs.de, providing your full name, matriculation number, TU email address, number of attempt, and degree program.

The repeat exams are usually held collectively. A date will be communicated to you in due time after registration.

Please note that besides the exam you need to have successfully participated in the exercises to successfully pass the module. The exercises are only offered when the course is held!

Supplementary Exam

If you need an oral supplementary exam because you have not passed the exam in your final regular attempt, please send an email requesting an oral supplementary exam to sekretariat@cg.cs.tu-bs.de immediately after receiving the grade (i.e., when it has been officially registered with the examination office), providing your full name, matriculation number, TU email address, and degree program.

The oral supplementary exams are usually held collectively once per semester. A date will be communicated to you in due time beforehand.
