(a) Vis-NIR reflectance spectrum of common plant leaves and camouflage coatings; (b) Infrared emissivity of camouflage coating and Epipremnum leaf; (c) The reflectance spectra of camouflage coatings in the 400–1000 nm band as temperature increases (measured by hyperspectral camera); (d) Humid (30 °C, 80%RH) and (e) dry (50 °C, 20%RH) environments for 5 days reflectance spectra of the coating; (f) Camouflage coating photographed under hyperspectral camera (Left is commercial camouflage netting, right is camouflage coating attached to a branch of bush); (g-h) Hyperspectral photographs at different SAM thresholds (Reference pixels are marked with an asterisk).
