This lecture will define spectral signature, spectral reflectance, as well as how these spectral signatures are useful in remote sensing-based analysis.
Mar 4, 2010 · Spectral signatures of rocks and mineral provide information on their chemical composition and crystal properties, grain size and roughness over a wide range of wavelengths from the visible to the thermal infrared.
A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum. It may result from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies.
Spectral signatures of image pixels are compared to the training spectral signatures; a pixel belongs to class X if pixel spectral signature is completely contained in the spectral region defined by class X.
Dec 3, 2018 · In this paper, we identify a new property of all known backdoor attacks, which we call spectral signatures. This property allows us to utilize tools from robust statistics to thwart the attacks. We demonstrate the efficacy of these signatures in detecting and removing poisoned examples on real image sets and state of the art neural ...
