Tomic functions and lacunary interpolation series in boundary value problems for partial derivatives equations and image processing
(ХАІ, 2020)
In the paper we consider and solve the problem of construction of the so called tomic functions – the systems of infinitely differentiable functions which while retaining many important properties of the shifts of atomic ...
On estimates of coefficients of generalized atomic wavelets expansions and their application to data processing
(ХАІ, 2020)
Discrete atomic compression of digital images is considered. It is a lossy compression algorithm. The aim of this paper is to obtain a mechanism for control of quality loss.
Two-step providing of desired quality in lossy image compression by SPIHT
(ХАІ, 2020)
This paper considers the application of the two-step method in an encoder based on a discrete wavelet trans-form (DWT).
