Comparison of algorithms for controlled pixel-by-pixel classification of noisy multichannel images
(ХАІ, 2019)
The subject of this study is the pixel-by-pixel controlled classification of multichannel satellite images distorted by additive white Gaussian noise. The paper aim is to study the effectiveness of various methods of image ...
Low SNR treshold in rapid estimators of complex sinusoidals
(ХАІ, 2016)
A task of estimation of complex sinusoid frequency is considered. A particular but practically important case of
low signal-to-noise ratio (SNR) is studied. The low SNR threshold, commonly overlooked in development 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 ...
Analysis of opportunities to improve image denoising efficiency for DCT-based filter
(ХАІ, 2018)
The subject matter of the paper is the process of image filtering. The goal is to provide high efficiency of denoising according to metrics that are more adequate to human vision system than traditional criteria as mean ...
