  • 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 ...
  • A study of image compression techniques, with specific focus on weighted finite automata 

    Muller, Rikus (Stellenbosch : University of Stellenbosch, 2005-12)
    Image compression using weighted finite automata (WFA) is studied and implemented in Matlab. Other more prominent image compression techniques, namely JPEG, vector quantization, EZW wavelet image compression and fractal ...
