Discrete atomic compression of digital images
(ХАІ, 2018)
The subject matter of this paper is the discrete atomic compression (DAC) of digital images, which is a lossy compression process based on the discrete atomic transform (DAT). The goal is to investigate the efficiency of ...
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).
