Wavelet Sets on Locally Compact Abelian Groups

پژوهش‌های ریاضی, 2020
Introduction An orthonormal wavelet is a square-integrable function whose translates and dilates form an orthonormal basis for the Hilbert space . That is, given the unitary operators of translation  for  and dilation , we call  an orthonormal wavelet if

Multiresolution Histogram Analysis for Color Reduction [PDF]

, 2010
A new technique for color reduction is presented, based on the analysis of the histograms of an image at different resolutions. Given an input image, lower resolution images are generated by using a scaling down interpolation method. Then, peaks and pits that are present in the histograms at all resolutions and dominate in the histogram of the input ...

A Method for Solving the Monge–Kantorovich Problem Using an Automaton and Wavelet Analysis

Mathematical and Computational Applications
This article introduces an automaton designed to improve feasible solutions to the Monge–Kantorovich (MK) problem, particularly effective when the cost function is continuous.

Mathematical Modeling of Learnable Discrete Wavelet Transform for Adaptive Feature Extraction in Noisy Non-Stationary Signals

Mathematics
The mathematical characterization of non-stationary signals remains a significant challenge, particularly when impulsive components are obscured by high-dimensional noise and structural coupling.

Compressive Data Hiding: An Unconventional Approach for Improved Color Image Coding

EURASIP Journal on Advances in Signal Processing, 2002
Traditionally, data hiding and compression have had contradictory goals. The former problem adds perceptually irrelevant information in order to embed data, while the latter removes this irrelevancy and redundancy to reduce storage requirements. In this
