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 ... -
Analysis of two-step approach for compressing texture images with desired quality
(ХАІ, 2020)A task of lossy compression of remote sensing and other types of images with providing the desired quality is considered. Quality is mainly characterized by the peak signal-to-noise ratio (PSNR) but visual quality metrics ... -
BPG-based compression analysis of Poisson-noisy medical images
(ХАІ, 2023)The subject matter is lossy compression using the BPG encoder for medical images with varying levels of visual complexity, which are corrupted by Poisson noise. The goal of this study is to determine the optimal parameters ... -
On classifier learning methodologies with application to compressed remote sensing images
(ХАІ, 2022)Remote sensing images have found numerous applications nowadays. A traditional outcome or intermediate result of their processing is a classification map. Such maps are usually obtained from a pre-trained classifier and ... -
On classifier performance for remote sensing images compressed by different coders
(ХАІ, 2023)The main subject of the article is the factors that determine the accuracy of the classification. One of them is the quality of the compressed image. -
On strange images with application to lossy image compression
(ХАІ, 2022)The task of the article is to provide a definition of strange images and check whether the non-monotonicity of the dependences of the distortions on the compression level holds for different encoders and metrics. Another ... -
Post-processing of compressed noisy images using BM3D filter
(ХАІ, 2023)The main goal of this paper is to consider the possible application of a block-matching 3-dimensional (BM3D) filter to images corrupted by additive white Gaussian noise compressed by a better portable graphics (BPG) coder ... -
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 ... -
Preliminary analysis of noisy image lossy compression by discrete atomic transform-based coder
(ХАІ, 2023)The main topic of this article is the features of lossy compression of a noisy image using an encoder based on atomic transformation. Our goal is to analyze whether the considered compression method provides the effect of ... -
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).
