In this paper a new scheme based on the wavelet type decomposition-reconstruction is proposed and experimentally verified. Instead of typical filters, i.e., those referring to the Fourier representation, half-band filters based on the discrete trigonometric transforms (DTTs) are used. A comparison with the standard approach has been performed and the… CONTINUE READING
