Implementation strategies for hyperspectral unmixing using Bayesian source separation. [PDF]

, 2010
Positive Source Separation (BPSS) is a useful unsupervised approach for hyperspectral data unmixing, where numerical non-negativity of spectra and abundances has to be ensured, such in remote sensing. Moreover, it is sensible to impose a sum-to-one (full

Deciphering the Palimpsest: Chronological Uncertainty and the Interpretation of Mining Landscapes at Písečný vrch (Czech Republic)

Archaeological Prospection, EarlyView.
ABSTRACT We investigated the Písečný vrch (Czech Republic), a site exploited for quartz mining in both prehistoric times and the 20th century. Due to their morphological similarity across all mining periods, the differentiation between pits with archaeological potential and recent ones is challenging.

A Spatial-Temporal Attention-Based U-Net for Crop Mapping from Time-Series Sentinel-2 Imagery: A Case in Sanjiang Plain

Remote Sensing
Food security is a growing global concern, and accurate crop mapping in major grain-producing regions like China’s Sanjiang Plain—which contributes approximately 7% of national grain output—is essential for agricultural resource management. However, crop

ISBDD Model for Classification of Hyperspectral Remote Sensing Imagery [PDF]

Sensors, 2018
The diverse density (DD) algorithm was proposed to handle the problem of low classification accuracy when training samples contain interference such as mixed pixels. The DD algorithm can learn a feature vector from training bags, which comprise instances (pixels).

Rethinking Separability Map: A Target-Specified Separability Map for Hyperspectral Target Detection

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Separability map (SM) is a widely used visualization tool for hyperspectral anomaly detection. It selects a fixed percentile range of [τSM%,100%-τSM%] and then uses it to construct an anomaly box (ax) and a background ...
