Abstract:
We present results on the expansion of elements of the spaces Lp(0,1), 0<p<1, into systems of functions that are contractions and shifts of one function. New algorithms are designed for the expansion of functions into Fourier-type series in these systems with integer coefficients. The expansions produced by the proposed methods have the property of image compression, i.e., a large number of expansion coefficients are zeros. The results may be of interest to specialists in the transmission and processing of digital information and to other researchers who have a need to expand nonintegrable functions into series in systems of contractions and shifts of one function.
Keywords:
functional systems of contractions and shifts of one function of the space Lp(0,1) with 0<p<1, Fourier-type series with integer coefficients, digital processing, information transmission.
