    • Automatic detection of image orientation using Support Vector Machines 

      Walsh, Dane A. (Stellenbosch : Stellenbosch University, 2002-12)
      ENGLISH ABSTRACT: In this thesis, we present a technique for the automatic detection of image orientation using Support Vector Machines (SVMs). SVMs are able to handle feature spaces of high dimension and automatically choose ...

    • Background subtraction algorithms for a video based system 

      Profitt, Barton (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 ...

    • The discrete pulse transform in two dimensions 

      Fabris-Rotelli, I. (Inger); Van der Walt, S. J. (Stefan J.) (Pattern Recognition Association of South Africa, 2009)
      During the last three decades, the LULU operator and its close relative, the Discrete Pulse Transform (DPT), were developed and applied to signal processing problems. Its recent extension into higher dimensions paved the ...

    • Morphing in two dimensions : image morphing 

      Delport, Magdil (Stellenbosch : University of Stellenbosch, 2007-12)
      Image morphing is a popular technique used to create spectacular visual effects, by gradually transforming one image into another. This thesis explains what exactly is meant by the terms “image morphing” / “warping”, where ...

    • Planar segmentation of range images 

      Muller, Simon Adriaan (Stellenbosch : Stellenbosch University, 2013-03)
      ENGLISH ABSTRACT: Range images are images that store at each pixel the distance between the sensor and a particular point in the observed scene, instead of the colour information. They provide a convenient storage format ...
