Biography
Karl Skretting was born in Nærbø, Norway in 1962. He is married to
Anita and they live in Sandnes. Some pictures of them and their daughters, Maria and
Anne, are available on the WWW.
Karl started to study
signal processing at University of Stavanger
(UiS) in 1996, the name then was Høgskolen i Stavanger
(HiS). He received his siv.ing. (M.Sc.)
degree from the Electrical and Computer Engineering Department in 1998.
In 2002 he received the Ph.D. degree. Currently, he is employed as associate
professor at UiS, and he is a part of the Cybernetics Group. The topics of
interest are signal representation, data compression, and computer graphics.
