Labs

During the lab sessions, you will be able to try out things learned in the lectures. Please come prepared! That means, go over the lectures again and read the relevant sections in the book. If you are properly prepared, you should be able to finish all the exercises during the lab session.

This semester (period 2) ends january 18th, so if all your labs are done (and corrected) by then you will get your course credits this semester. Otherwise you will not get your credits until the reexam in April.

Examination

Exam 2014-12-18 (8:00-13:00, Pollacksbacken skrivsal).
Re-exam 2015-04-09 (8:00-13:00 Pollacksbacken skrivsal)

The labs are mandatory and for each lab finished before its deadline you will receive bonus points on the written exam (the exam will have a total of 40 points). If you cannot attend a lab, you are welcome to email a report to the lab assistants. Labs handed in during the course will be corrected as soon as possible.

On the written exam you will be allowed to carry one sheet (two sides) with hand-written notes. Preparing your own notes for the exam is a helpful studying technique, and we see little point in memorizing things.

Old exams:

Literature

Most of the lectures are based on this book:

  • R. C. Gonzalez and R. E. Woods, "Digital Image Processing",3rd. ed. : Upper Saddle River, N.J. : Prentice Hall, cop. 2008, ISBN: 978013505267-9.

You can get it (or order it) at e.g. Studentbokhandeln AB here in Uppsala or online, for example at: adlibris.com or bokus.com. A few books are also available through libraries.

Copies of slides and other material will be handed out during most of the lectures. The written exam is based on content covered in the lectures (oral presentation, lecture notes and blackboard examples). The book is highly recommended for background information and details about methods and theory.
