Sharp inequalities of various metrics on the classes of functions with given comparison function

Researches in Mathematics, 2021
For any $q > p > 0$, $\omega > 0,$ $d \ge 2 \omega,$ we obtain the following sharp inequality of various metrics $$ \|x\|_{L_q(I_{d})} \le \frac{\|\varphi + c\|_{L_q(I_{2\omega})}}{\|\varphi + c \|_{L_p(I_{2\omega})}} \|x\|_{L_p(I_{d})} $$ on the ...

Lossy Compression using Adaptive Polynomial Image Encoding

Advances in Electrical and Computer Engineering, 2021
In this paper, an efficient lossy compression approach using adaptive-block polynomial curve-fitting encoding is proposed. The main idea of polynomial curve fitting is to reduce the number of data elements in an image block to a few coefficients.

Image inpainting-based behavior image secret sharing

Mathematical Biosciences and Engineering, 2020
The polynomial-based image secret sharing (ISS) scheme encodes a secret image into n shadows assigned to n participants. The secret image with high resolution is decoded by Lagrange interpolation when collecting any k or more shadows.

Polynomial, Neural Network, and Spline Wavelet Models for Continuous Wavelet Transform of Signals

Sensors, 2021
In this paper a modified wavelet synthesis algorithm for continuous wavelet transform is proposed, allowing one to obtain a guaranteed approximation of the maternal wavelet to the sample of the analyzed signal (overlap match) and, at the same time, a ...
