Fast wavelet-based pansharpening of multi-spectral images [PDF]

open access: yes, 2010
Remote Sensing systems enhance the spatial quality of low-resolution Multi-Spectral (MS) images using information from Pan-chromatic (PAN) images under the pansharpening framework. Most decimated multi-resolution pansharpening approaches upsample the low-

Quantification of short‐term transformations of proglacial landforms in a temperate, debris‐charged glacial landsystem, Kvíárjökull, Iceland

open access: yesLand Degradation &Development, Volume 34, Issue 17, Page 5566-5590, November 2023., 2023
Abstract Proglacial areas are dynamic landscapes and important indicators of geomorphic changes related to climate warming. Systematic and repeat surveys of landforms presently evolving on glacier forelands facilitate the quantification of rates of change and an improved understanding of the processes generating those changes.

A Spectral-Aware Convolutional Neural Network for Pansharpening

open access: yesApplied Sciences, 2020
Pansharpening aims at fusing a low-resolution multiband optical (MBO) image, such as a multispectral or a hyperspectral image, with the associated high-resolution panchromatic (PAN) image to yield a high spatial resolution MBO image.

A Deep-Shallow Fusion Network With Multidetail Extractor and Spectral Attention for Hyperspectral Pansharpening

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Hyperspectral (HS) pansharpening aims at fusing a low-resolution HS image with a high-resolution panchromatic (PAN) image to obtain a HS image with both higher spectral and spatial resolutions.

Satellite image survey of beluga whales in the southern Kara Sea

open access: yesMarine Mammal Science, Volume 39, Issue 4, Page 1204-1214, October 2023., 2023
Abstract The use of satellite imagery to find, count and monitor whales in remote and hard to access areas has shown some promise, but few satellite studies have, as yet, provided substantial conservation outcomes. Recent studies have shown the ability of very high‐resolution satellites to detect and count previously surveyed populations of belugas and

Enhanced Back-Projection as Postprocessing for Pansharpening

open access: yesRemote Sensing, 2019
Pansharpening is the process of integrating a high spatial resolution panchromatic image with a low spatial resolution multispectral image to obtain a multispectral image with high spatial and spectral resolution. Over the last decade, several algorithms

THE EFFECT OF PANSHARPENING ALGORITHMS ON THE RESULTING ORTHOIMAGERY [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
This paper evaluates the geometric effects of pansharpening algorithms on automatically generated DSMs and thus on the resulting orthoimagery through a quantitative assessment of the accuracy on the end products. The main motivation was based on the fact

Batagay megaslump: A review of the permafrost deposits, Quaternary environmental history, and recent development

open access: yesPermafrost and Periglacial Processes, Volume 34, Issue 3, Page 399-416, July/September 2023., 2023
Abstract The Batagay megaslump, in the Yana Uplands of northern Yakutia, Russia, is the largest known retrogressive thaw slump in the world. The slump exposes a remarkable sequence of Ice Age permafrost deposits that record the interaction of colluvial, eolian and periglacial processes on a hillslope episodically forested during the last 650 ka or more

Pansharpening techniques to detect mass monument damaging in Iraq [PDF]

open access: yes, 2017
The recent mass destructions of monuments in Iraq cannot be monitored with the terrestrial survey methodologies, for obvious reasons of safety. For the same reasons, it’s not advisable the use of classical aerial photogrammetry, so it was obvious to ...

Active temperate glacial landsystem evolution in association with outwash head/depositional overdeepenings

open access: yesEarth Surface Processes and Landforms, Volume 48, Issue 8, Page 1573-1598, 30 June 2023., 2023
We present a locally diverse process‐form model of incremental stagnation in an active temperate glacier landsystem based on mapping and quantification of historical landscape change on the Fjallsjökull‐Hrútárjökull foreland, SE Iceland. Glacier snout behaviour since 1945 highlights the importance of: 1) the development and collapse of partially ...
