A New Rule-Based Classification Method Using Shape-Based Properties of Spectral Curves

Figure 21

Spectra of measured plants. Two different cameras were used to acquire the spectra (Specim FX10 and Specim FX17). The discontinuities in the range of 900 nm and the greater noise in the VIS range can be explained by the differences in spectral sensitivity of the cameras. In particular, the range below 500 nm exhibits strong noise effects and was not considered in the rule formation. Taraxacum (1), Inula conyza (2), Campanula rotundifolia (3), moss (4), Geranium robertianum (5), Asplenium trichomanes (6), green sedum (7), red sedum (8), moss (9), and lichen (10).
