Sub-pixel Mapping Method based on Total Variation Minimization and Spectral Dictionary
2020 5th International Conference on Advanced Technologies for Signal and Image Processing (ATSIP), 2020In this paper we tackle the problem of data analysis over the higher dimensional space provided by hyperspectral images. Remote sensing data analysis is a complex task due to numerous factors such as the large spectral and spatial diversity. The latter is the key focus of attention in this paper.As a matter of fact, mixed pixels are often sources of ...

Use of spectral library searching as an automated method of analysing hyperspectral remote sensing data for material mapping is gaining prominence, especially in the mineral mapping domain. The possibility and reliability of material identification by the spectral library search approach depends on the spectral representation, characterized by spectral

Spectral methods for forward-propagating water waves in conformally-mapped channels
Applied Ocean Research, 1994Abstract The prediction of wave fields in domains with complicated geometries may be aided by the use of conformal-mapping, which simplifies the shape of the domain. In this conformal domain, parabolic models have been used previously to treat wave problems.

Urban landcover mapping using different spectral mixture analysis methods
SPIE Proceedings, 2009The complex spatial and spectral variability of urban structures present fundamental challenges to deriving accurate remote sensing information for urban areas. Spectral mixture analysis (SMA), based on a physical mixture model, has ability to extract sub-pixel information such as the abundances of each endmember presented in the pixel (image unity).

Mapping oil contaminated sand and till by spectral induced polarization method
56th EAEG Meeting, 1994Mapping soils polluted by toxic organic liquids forms a problematic task for electrical methods. Organic liquids are typically poor conductors and their influence on the resistivity of soil remains small even at high concentrations. The possibility of monitoring organic contaminations by the induced polarization (IP) method was proposed in the middle ...

Spectral induced polarization method in mapping soils polluted by organic chemicals
54th EAEG Meeting, 1992Application of electric and electromagnetic methods in mapping polluted areas is based on the increase of electrical conductivity of the soil due to the contaminants. Problems with these methods arise when pollutants are organic chemicals. They are often poor conductors and their effect on the resistivity of soil remains small even in high ...

A non-invasive spectral reflectance method for mapping blood oxygen saturation in wounds
Applied Imagery Pattern Recognition Workshop, 2002. Proceedings., 2003Reflectance spectroscopy is a common technique used to analyze blood oxygen saturation in biological tissues. This study describes a non-invasive method for mapping blood oxygen saturation in wounds using reflectance measurements obtained from a hyperspectral imaging system.
