• Applying the MDCT to image compression 

      Muller, Rikus (Stellenbosch : University of Stellenbosch, 2009-03)
      The replacement of the standard discrete cosine transform (DCT) of JPEG with the windowed modifed DCT (MDCT) is investigated to determine whether improvements in numerical quality can be achieved. To this end, we employ ...
    • Image compression using the one-dimensional discrete pulse transform 

      Uys, Ernst Wilhelm (Stellenbosch : University of Stellenbosch, 2011-03)
      ENGLISH ABSTRACT: The nonlinear LULU smoothers excel at removing impulsive noise from sequences and possess a variety of theoretical properties that make it possible to perform a so-called Discrete Pulse Transform, which ...
