“…Assessment of chromatic similarity between animal and background spectra using a nonbiological measure (Spectral Angle Mapper) In the field of remote sensing, automated spectral library search algorithms developed for hyper-spectral images (Chang 2003;Sweet 2003;Freek 2006;Nidamanuri and Zbell 2011) are used to compare reflectance spectra of known targets to those of novel spectra by computing a scalar similarity score between them. For these algorithms, stochastic methods are more frequently used than deterministic methods because imaging conditions can be imperfect and because the high spectral resolution of a hyper-spectral sensor often results in more than one material spectral signature in a given pixel.…”

“…For this purpose, power of spectral discrimination (PWSD) is utilized, which was proposed in [30]. PWSD provides an assessment criterion depending on two reference cluster centers for a particular pixel.…”

“…Heiden et al [4] numerically describe the spectral reflectance curve using various feature functions, such as mean, standard deviation and ratios of the reflectance between two wavelengths, by the area under the feature in the spectrum, and by the absorption depth and position. Spectral matching techniques assess the similarity of an image spectrum to a known class spectrum [125,126]. Examples of similarity measures are spectral information divergence (SID) [127], Euclidean distance (ED) or spectral angle mapper (SAM) [128].…”
