Multi-Scale Pixel-Based Image Fusion Using Multivariate Empirical Mode Decomposition
Sensors, 2015 A novel scheme to perform the fusion of multiple images using the multivariate empirical mode decomposition (MEMD) algorithm is proposed. Standard multi-scale fusion techniques make a priori assumptions regarding input data, whereas standard univariate ...

Journal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.Abstract Purpose To overcome limitations of conventional VMAT for cervical cancer, specifically restricted OAR sparing due to static collimators and delivery constraints inherent to dynamic modulation, we systematically evaluate RapidArc Dynamic (RAD) technology. This first comprehensive assessment focuses on RAD's multi‐axis coordination for optimized

A Detail-Preserving Cross-Scale Learning Strategy for CNN-Based Pansharpening
Remote Sensing, 2020 The fusion of a single panchromatic (PAN) band with a lower resolution multispectral (MS) image to raise the MS resolution to that of the PAN is known as pansharpening.

Advanced Energy and Sustainability Research, Volume 7, Issue 2, February 2026.This study investigates real‐time forecasting for renewable energy management using solar photovoltaic data. By analyzing over 100 million multiresolution data points, the authors show that forecasting accuracy depends on time resolution, with different models excelling at different scales.

Adaptive Wavelet Thresholding for Multiresolution Denoising Based on Image Size
Engineering ProceedingsHard thresholding is a common method for denoising wavelet coefficients. However, determining an optimal threshold remains challenging. Therefore, we propose an adaptive hard threshold that accounts for the size of the noisy image based on the ...

Geometric-textured bitree: transmission of a multiresolution terrain the Internet
Journal of Computer Science and Technology, 2002 Transmission of large terrain databases across the Internet is still worrying. A large terrain database requires a big number of polygons and textures, and that represents a problem with current bandwidth and resource limitations.

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
