Course information

The lectures are given in building 321, room H033, on Thursdays from 1 pm – 2.30 pm (approximately). The computer exercises take place immediately after the lectures in the same room; a teaching assistant will be present. The computer exercises are on the topic of the current week’s lecture. The exercises should be carried out in groups of 2-3.

Lecture notes and exercise texts and materials are available through CampusNet.

How to pass this course

For each subject considered in the course an exercise is carried out and an exercise report must be prepared and handed in. The course examination consists of an oral examination in the course topics based on the course theory and exercise reports. The oral examination will be held during the period 7-21 December 2018 (the exact date will be announced later).

This is a 5 ECTS point course corresponding to a work load of 8-10 hours work per week and most of this time is used to implement the image analysis models in the exercises. Some of the algorithms are complicated and the computations can be time-consuming. You can only understand these algorithms fully by implementing them, so that you can test the effect of varying data and parameters. Hence a successful completion of the course (and exam) requires that your implementation works and that you demonstrate a good understanding of the strengths and weaknesses of the models.
