Background subtraction algorithms for a video based system
(Stellenbosch : University of Stellenbosch, 2009-12)
ENGLISH ABSTRACT: To reliably classify parts of an image sequence as foreground or background is an important part of many computer vision systems, such as video surveillance, tracking and robotics. It can also be important ...
Fast generation of digitally reconstructed radiographs for use in 2D-3D image registration
(Stellenbosch : Stellenbosch University, 2008-12)
A novel implementation exploiting modern hardware is explored and found to be a significant improvement over current methods used. A 50 times performance increase in the computation time of DRRs is achieved over the ...
A categorical study of compactness via closure
(Stellenbosch : Stellenbosch University, 2009-03)
We have the familiar Kuratowski-Mr owka theorem in topology, where compactness is characterised by a closure and a projection-map (X is compact i p : X Y ! Y is a closed mapping, for any space Y , i.e. p(A) = p(A) A ...
