TSBB15 Computer Vision VT2020 (last year's course)
This course is given during the VT1 and VT2 periods. Note that not all the time slots in the course schedule will be used. A few spare slots have been reserved in case a lecture has to be moved. The actually planned lectures are listed below on this page, and any changes to this plan will be announced during the lectures, and on this page.
Registration
If you intend to take the course but are not registered, make sure to register ASAP in Ladok, using the Student portal.

Literature
In the course we will mainly use the following two books:
- Klas Nordberg, Introduction to Representations and Estimation in Geometry (IREG).
This compendium covers only the 3D geometry part of the course. - Richard Szeliski, Computer Vision: Algorithms and Applications, Springer Verlag (2011).
This book covers topics such as tracking, optical flow and image features.
The book is available as an on campus e-book via the LiU library. See also Book webpage.
Other topics covered in the course, such as background models are missing from these two. For side reading on other topics, we have collected pointers to relevant literature in the column "Material" in the "Lecture and Lab schedule" below.
Examination
- 2020-03-24, 14-18: Re-examination opportunity for last year's students (TEN1), and voluntary mid-term examination for this years's students (KTR1).
- 2020-06-02, 14-18: Examination at end of course.
- 2020-08-18, 14-18: Re-examination opportunity.
At present the exams are done remotely, and access to reference material is allowed (this is called "distance exams" by LiU). The exams are handed in as PDFs using Lisam. If you intend to take an exam and are not registered on the course, you should contact the examiner to be added to the Lisam course room.
Old exams
The exams from 2014, 2018 and 2019 in TSBB15 can be found here.
How to use the old exams: We recommend that you use these exams as pointers into the literature ("instuderingsfrågor"). To answer the exam, read corresponding discussions in your notes, the course book, and the lecture slides. While it is faster to look at other people's exam answers, this merely gives you answers, while reading and thinking also results in understanding.
Grades
How to pass the course, and the grading criteria are described here.

General resources
We suggest and allow you to use the following software:
- OpenCV
(Open Source Computer Vision). Version 3.4.3 is installed
on the department's Linux computers (first you need to issue the module add prog/opencv/3.4.3 command). See also the minimal example OpenCV progam (contributed by Gustav Häger).
Read the section on OpenCV in the hints and pitfalls page. There is a cheat sheet for OpenCV. An important exception is the Background modelling with mixtures of Gaussians, which you are NOT allowed to use (as you're supposed to learn this in the course). - Python with OpenCV bindings. Python 3.6.9 is installed in the computer labs. Essential libraries such as Matplotlib, NumPy, and SciPy are also available.
- VLFeat has a a useful code library, both for Matlab and C/C++. For example, it has an alternative implementation of SIFT, and also an implementation of MSER. Both are made by Andrea Vedaldi.
- The Visual Geometry Group at Oxford University maintains code for affine invariant region detectors, produced in cooperation with other groups.
- The Computer Vision Laboratory at ETH provides an implementation of SURF.
- An IDE, e.g. PyCharm community edition, which is installed in the computer labs after loading the right module (see module avail) (remember to say no to creation of a shortcut on /usr/local when you start pycharm).
Project repositories
Project code should be developed under versioning control, with changes tracked according to LiU-ID of the participating group members.
- Project groups get their repositories from GITLab at IDA, or the LiU Git. Note: this is not GitHub, and GitHub should not be used.
- Project guides and examiner should be given "reporter" access to the group repositories.
Hints and pitfalls
Based on experience from previous year's projects, we have accumulated a list of hints and pitfalls for the projects. Read them carefully before starting your project work.
