Adaptive two-step method for providing the desired visual quality for SPIHT
(ХАІ, 2022)
is employed to evaluate the image quality. The research method is based on a validation ex periment that is
conducted for an image set covering different image complexity and texture features. The comparison results ...
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.
Prediction of compression ratio for ADCT coder
(ХАІ, 2016)
One way to predict compression ratio for efficient coder called ADCT is proposed. Prediction is based on determination
of a simple parameter before compression that can be easily calculated in 8x8 pixel blocks. Such ...
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).
