  • An Approach to 2D Wavelet Transform and Its Use for Image Compression 

    Vargic, R. (Společnost pro radioelektronické inženýrství, 1998-12)
    In this paper is constructed a new type of two-dimensional wavelet transform. Construction is based on lifting scheme. We transform 1D wavelets with symmetrical factorisation to their 2D counterparts. Comparison to existing ...
  • On the Relationship between Integer Lifting and Rounding Transform 

    Prochaska, J.; Vargic, R. (Společnost pro radioelektronické inženýrství, 2007-12)
    In this paper we analyze the relationship between integer Lifting scheme and Rounding transform as means to compute the wavelet transform in signal processing area. We bring some new results which better describe relationship, ...
  • Using Digital Filtration for Hurst Parameter Estimation 

    Prochaska, J.; Vargic, R. (Společnost pro radioelektronické inženýrství, 2009-06)
    We present a new method to estimate the Hurst parameter. The method exploits the form of the autocorrelation function for second-order self-similar processes and is based on one-pass digital filtration. We compare the ...
