Minimalistic System of Characteristics of Non-linear Baseband Pulse Devices and Its Measurement

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2023
Introduction. The general system of parameters, including compression points and intersection points of various harmonics, is unsuitable for devices operating under the influence of baseband pulses (for example, before the modulator in the transmitter ...

Recursive Prediction for Lossless Image Compression

open access: yesIraqi Journal of Science, 2021
     This paper introduced an algorithm for lossless image compression to compress natural and medical images. It is based on utilizing various casual fixed predictors of one or two dimension to get rid of the correlation or spatial redundancy embedded between image pixel values then a recursive polynomial model of a linear base is used. The ...

Local Excitation Network for Restoring a JPEG-Compressed Image

open access: yesIEEE Access, 2019
Joint photographic experts group (JPEG) compression is lossy compression, and degradation of image quality worsens at high compression ratios. Therefore, a reconstruction process is required for a visually pleasant image. In this paper, we propose an end-

Compressing Graphs and Indexes with Recursive Graph Bisection [PDF]

open access: yesProceedings of the 22nd ACM SIGKDD International Conference on Knowledge Discovery and Data Mining, 2016
Graph reordering is a powerful technique to increase the locality of the representations of graphs, which can be helpful in several applications. We study how the technique can be used to improve compression of graphs and inverted indexes. We extend the recent theoretical model of Chierichetti et al.

Recursive Compressed Sensing

open access: yes, 2013
We introduce a recursive algorithm for performing compressed sensing on streaming data. The approach consists of a) recursive encoding, where we sample the input stream via overlapping windowing and make use of the previous measurement in obtaining the next one, and b) recursive decoding, where the signal estimate from the previous window is utilized ...

A Wavelet-Based Steganographic Method for Text Hiding in an Audio Signal

open access: yesSensors, 2022
The developed method of steganographic hiding of text information in an audio signal based on the wavelet transform acquires a deep meaning in the conditions of the use by an attacker of deliberate unauthorized manipulations with a steganocoded audio ...

A Contextual Hybrid Model for Vessel Movement Prediction

open access: yesIEEE Access, 2021
Predicting the movement of the vessels can significantly improve the management of safety. While the movement can be a function of geographic contexts, the current systems and methods rarely incorporate contextual information into the analysis.
