Computer Vision - Image Understanding - Bildverstehen
Exam WS 2017-18
The grades have been transmitted to the examination office. You can have a look at your work ONLY during the speaking hours: Mondays from 13:00 to 14:00 in 1/348.
Prerequisites: Modules in Mathematics I to IV, basic knowledge in Python.
Exam: written examination (90 minutes), 5 credit points.
Contact: julien dot vitay at informatik dot tu-chemnitz dot de.
Language: English. The written exam can of course be done in German.
Note: there is no retake exam in the summer semester.
The course is an introduction to computer vision, from basic image processing (filters, Fourier transformation) to more advanced algorithms (object recognition, movement, facial features extraction).
- Image formation
- Image processing
- Geometric transformations
- Feature detection and matching
- Motion, optical flow
The exercises are made on computers using the OpenCV computer vision library with the Python bindings.
The course is based primarily on the textbook by Richard Szeliski:
Richard Szeliski (2010). Computer Vision: Algorithms and Applications. Springer.
A free online draft is available at szeliski.org/Book/
The online book by Simon Prince, Computer vision: models, learning and inference (available at computervisionmodels.com) might also be helpful.
- How do I register for the course?
You don't. There is no OPAL or anything, just show up to the lectures/exercises and register for the exam in December.
- How do I register for the exam?
Registration on SBService will start in December.
- I cannot assist to the exercises. Can I take the exam anyway?
Yes. The exercises are there to help you understand the concepts seen in the lectures and get practical experience with computer vision tools. But they are not important for the exam.
- Do I have to memorize all these equations?
No, but to understand them, which is basically the same.
- I failed the exam in the winter semester. Can I retake it in the summer semester, otherwise I will not be able to finish my Master thesis?
No, exams are in the winter semester only, no exception. Come prepared to the exam if you are under time pressure.
