Region analysis of simple invisible scenes. (a) Pseudo-color diagram synthesized by HSI (R:598.60 nm, G:548.55 nm, B:449.35 nm); (b) SAM classification results; (c) Noise reduction applied to (b); (d) (c) applied to (a); (e) Regional spectral analysis. The curve “SheepNew” is the result of “Sheep”−“Bar”. In (b) and (c), the imagery is distinctly presented in two colors. To differentiate, the green area is named as “Sheep,” and the red area as “Human”
