Refined Modeling of Arctic Circumpolar Building Stock Increases Estimated Mid‐Century Permafrost Degradation Damages

Earth's Future, Volume 14, Issue 7, July 2026.
Abstract Near‐surface permafrost degradation has the potential to damage infrastructure needed to sustain Arctic communities, but risk assessments remain highly uncertain due to a limited representation of the Arctic circumpolar building stock. With deep learning building footprint detection and building occupancy classification models, we expand the ...

Pansharpening using total variation regularization [PDF]

, 2012
International audienceIn remote sensing, pansharpening refers to the technique that combines the complementary spectral and spatial resolution characteristics of a multispectral image and a panchromatic image, with the objective to generate a high ...

Simultaneous Generation of Topographic Models and Manning Roughness Coefficient Maps From Tri‐Stereoscopic Satellite Images: Application to the Huarmey River, Peru

The Photogrammetric Record, Volume 41, Issue 195, July‐September 2026.
Tri‐stereoscopic PeruSat‐1 imagery enables the simultaneous generation of 0.70 m‐resolution topography and spatially distributed Manning roughness maps, achieving 0.434 m vertical accuracy. Integrated into HEC‐RAS, these products provide consistent, high‐resolution inputs that improve hydraulic modelling and flood risk assessment in data‐scarce river ...

MULTISPECTRAL PANSHARPENING APPROACH USING PULSE-COUPLED NEURAL NETWORK SEGMENTATION [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
The paper proposes a novel pansharpening method based on the pulse-coupled neural network segmentation. In the new method, uniform injection gains of each region are estimated through PCNN segmentation rather than through a simple square window.

A Metaheuristic Optimization-Based Solution to MTF-GLP-Based Pansharpening

, 2023
In recent years, the pansharpening strategies employing the Generalized Laplacian Pyramid (GLP) based on Gaussian filters that match the Modulation Transfer Function (MTF) of the source multispectral (MS) sensor have attracted attention in remote sensing

Mechanisms of Surface Meltwater Ponding and Drainage on the Greenland Ice Sheet Revealed Using SkySat Imagery and Deep Learning

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surface meltwater impacts Greenland Ice Sheet mass balance indirectly by reducing albedo and promoting hydrofracture. However, fully understanding both processes requires accurate mapping of small‐scale features such as ponds, channels, and moulins that govern meltwater formation and drainage. Here we investigate surface water dynamics at high

A cross-band transformer on wavelets for pansharpening of satellite imagery

European Journal of Remote Sensing
Pansharpening is the task of fusing panchromatic and low-resolution multi-spectral data to obtain a high-resolution equivalent. In our study, we develop a cross-band transformer (CBT) method for pansharpening, incorporating and adapting successful ...

Adaptive Feedback‐Driven Gram‐Schmidt Pansharpening: An Iterative Quality Enhancement Framework

IET Image Processing, Volume 20, Issue 1, January/December 2026.
We propose an adaptive feedback‐driven pansharpening (AFDP) framework that enhances the classical Gram‐Schmidt (GS) method by iteratively refining the fusion process using low‐pass‐filtered updates and a QNR‐based stopping criterion. Unlike traditional GS sharpening, which injects panchromatic details in a single step, the AFDP approach gradually ...

Image Restoration for the MRA-Based Pansharpening Method

IEEE Access, 2020
By merging high-resolution panchromatic (PAN) images with low-resolution multispectral (MS) images, high-resolution MS images with complementary information can be obtained, i.e., pansharpening.

Semi‐Automated Detection of Right Whales (Eubalaena spp.) in Very High‐Resolution Satellite Imagery

Marine Mammal Science, Volume 41, Issue 4, October 2025.
ABSTRACT Space‐based detection of whales is proliferating because it shows promise as a monitoring tool, yet tests of its application across taxa and environments are rare. The objective of this study was to develop an end‐to‐end, semi‐automated procedure for detecting two right whale species ( Eubalaena glacialis and E.
