3D curvelet transforms and astronomical data restoration
Applied and Computational Harmonic Analysis, 2010 The authors extend the curvelet transform from 2D to 3D. They propose two new decompositions, the BeamCurvelet and the RidCurvelet. The authors show that these new 3D transforms are useful for different applications such as filament detection, 3D cosmological data denoising and inpainting.

Active Seismic Exploration of Planetary Subsurfaces via Compressive Sensing
Earth and Space Science, Volume 12, Issue 3, March 2025.Abstract Geophysical measurements, such as seismic experiments, are a key target for scientific activities on planetary surfaces. Dense spatial sampling of such measurements is often desirable, and acquisition is traditionally performed at regular intervals.

An integrated scheme to improve pan-sharpening visual quality of satellite images
Egyptian Informatics Journal, 2015 Pan-sharpening is the process to fuse a low-resolution multispectral (MS) image with a high-resolution panchromatic (Pan) image to construct high spatial and spectral resolution MS image.

Continuous Curvelet Transform: II. Discretization and Frames [PDF]
, 2005 We develop a unifying perspective on several decompositions exhibiting directional parabolic scaling. In each decomposition, the individual atoms are highly anisotropic at fine scales, with effective support obeying the parabolic scaling principle length

Detection and Characterisation of Atypical Harmonic Patterns in Big Power Quality Data
IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.This paper proposes a new algorithm to identify and assess properties of atypical harmonic patterns in long‐term monitoring data adaptively. The well‐known challenges of field application, such as data accuracy validation, missing data handling, adaptability to dynamic data nature (seasonality and trends), and data mining results interpretation, are ...

Multi-focus Image Fusion Using Curvelet Transform [PDF]
Proceedings of the 2nd International Symposium on Computer, Communication, Control and Automation, 2013 Curvelet transform is a new muiti-scale geometic analysis, which has the characteristics of anisotropy. It is more suitable for the analysis of image curve edge characteristics than wavelet. Thus, in this paper it is applied to multi-focus image fusion, and used fusion rules that suitable for the characteristics of multi-focus image fusion.

Sparse representation for restoring images by exploiting topological structure of graph of patches
IET Image Processing, Volume 19, Issue 1, January/December 2025.To elevate sparse representation learning, this study leverages a graph learning model to delineate similarity relationships among image patches, utilizing this model for the initial image reconstruction phase. To capitalize on inter‐patch relationships while preserving individual patch characteristics, low‐rank constraints are integrated during the ...
