Pågående forskning

I am writing a review on Optical Flow and its estimation and applications.


Teaching experience (full courses)

From 1990 I initiated and taught the courses Signal Processing and Image Processing for the Master students. Since then Signal Processing has been lectured by several professors in the Signal Processing Group.

My interest has mainly been in the development of the image processing course. From 2005 the subject was divided into two parts, an introductory part with traditional image processing and a second part with Computer Vision - Machine Vision. From 2012 we renamed the course to Image Processing with Robot Vision (ELE510).

I have also lectured several courses for the Bachelor Students in Electrical Engineering, since the nineteen eighties. The last years I have lectured an introductory course in Electrical Engineering (ELE100).


Board positions

Since 2006 I have been chairman for the election committee at the university. The election committee is responsible for the election of rector of the university, board members to the university board and faculty boards.

I have been treasurer for the board of the association of researchers (Forskerforbundet) at UiS from 2011-2017.
