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 ...

Image Restoration for the MRA-Based Pansharpening Method
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.

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 ...

Variable Subpixel Convolution Based Arbitrary-Resolution Hyperspectral Pansharpening
International audienceStandard hyperspectral (HS) pansharpening relies on fusion to enhance low-resolution HS (LRHS) images to the resolution of their matching panchromatic (PAN) images, whose practical implementation is normally under a stipulation of ...

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

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

Joint multichannel pansharpening for multispectral imagery [PDF]
Pan-sharpening is a common post-processing operation for captured multispectral satellite imagery, where the spatial resolution of images gathered in various spectral bands is enhanced by fusing them with a panchromatic image captured at a higher resolution.

Learning an Efficient Convolution Neural Network for Pansharpening
Pansharpening is a domain-specific task of satellite imagery processing, which aims at fusing a multispectral image with a corresponding panchromatic one to enhance the spatial resolution of multispectral image.

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