Singular spectrum analysis for effective feature extraction in hyperspectral imaging

, 2014
As a very recent technique for time series analysis, Singular Spectrum Analysis (SSA) has been applied in many diverse areas, where an original 1D signal can be decomposed into a sum of components including varying trends, oscillations and noise ...

Spatial Cell Death and Oxidative Stress Dynamics in Gas Plasma‐Treated Tumor Tissues

Advanced NanoBiomed Research, EarlyView.
Schematic representation of the four experimental models to study tissue penetration and oxidation. Four tissue models were used. Human pancreatic cancer cells were grown on the chorioallantois membrane of chicken embryos and gas plasma‐treated in ovo, murine colorectal tumor tissue was gas plasma‐exposed ex vivo, murine squamous cell carcinoma cells ...

Leveraging Hyperspectral Data in Cognitive Environments

IEEE Access
Hyperspectral Imaging (HSI) captures data across multiple wavelengths of light, including visible and non-visible spectra (e.g., infrared or ultraviolet). It is usually used to analyze the composition, structure, and condition of objects of interest in a given environment through the spectral signature that, for a given material, represents its unique ...

Hyperspectral Image Resolution Enhancement Based on Spectral Unmixing and Information Fusion

, 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.

Bayesian estimation of linear mixtures using the normal compositional model. Application to hyperspectral imagery [PDF]

, 2010
This paper studies a new Bayesian unmixing algorithm for hyperspectral images. Each pixel of the image is modeled as a linear combination of so-called endmembers.

Generative AI, ESG Sensemaking, and Environmental Performance: an OIPT Perspective

Business Strategy and the Environment, EarlyView.
ABSTRACT Despite growing enthusiasm for generative artificial intelligence (GenAI) in sustainability management, it remains unclear how such technologies translate vast ESG information into meaningful environmental outcomes. This study addresses this gap by investigating how ESG sensemaking capability mediates the relationship between GenAI integration
