SNMF-Net: Learning a Deep Alternating Neural Network for Hyperspectral Unmixing [PDF]

open access: yes, 2021
Hyperspectral unmixing is recognized as an important tool to learn the constituent materials and corresponding distribution in a scene. The physical spectral mixture model is always important to tackle this problem because of its highly ill-posed nature.

Hyperspectral Image Resolution Enhancement Based on Spectral Unmixing and Information Fusion [PDF]

open access: yes, 2011
Hyperspectral imaging sensors exibit high spectral resolution, but normally low spatial resolution. This leads to spectral signatures of pixels originating from different object types. Such pixels are called mixed pixels.

Remote Sensing for Monitoring and Managing Urban Soils in Coastal Areas: A Review

open access: yesSoil Use and Management, Volume 42, Issue 3, July‐September 2026.
ABSTRACT Coastal urban soils (CUS) exhibit distinct physical–chemical properties due to the combined effects of intense interaction among anthropogenic and natural pressures, resulting in a unique, complex and highly vulnerable system. While CUS are vital for the urban coastal environment and its inhabitants, numerous factors significantly threaten ...

Bayesian separation of spectral sources under non-negativity and full additivity constraints [PDF]

open access: yes, 2009
This paper studied Bayesian algorithms for separating linear mixtures of spectral sources under non-negativity and full additivity constraints. These two constraints are required in some applications such as hyperspectral imaging and spectroscopy to get ...
