A hypothesis about efficient Mallat scheme decomposition stage with the use of filters derived from the 16 DTTs, instead of the wavelet convolution filters, was discussed. Introduction of windowing in the time domain resulted in considerable reduction of computations, up to 34 times, while the accompanying distortion was assessed at the PSNR level about 40 dB. The investigation was performed with statistically defined signals, based on the first-order Markov process with an assumed intersymbol correlation.
