Spectral reflectance estimation seeks to recover the full wavelength-dependent reflectivity profile of a surface from the limited sensor channels of a digital imaging system. By modelling the ...

Spectral imaging for conservators offers the promise of providing a non-destructive tool for the identification of artists’ materials in situ, as well as determining their spatial distribution in an ...

Field spectroscopy enables scientists to measure how different materials interact with electromagnetic energy and therefore underpins the technology enabling us to view the world from the air or space ...

Electromagnetic reflectance and emissivity are complementary radiative properties describing how materials interact with incident and thermally emitted electromagnetic radiation as a function of ...

Digital imaging that includes spectral estimation can overcome limitations of typical digital photography, such as limited color accuracy and constraints to a predefined viewing condition or a ...
