Within- and between- class variability of spectrally similar tree species

Author: Debba, Pravesh ; Cho, Moses A ; Mathieu, Renaud SA Date: Jul 2009 In this paper, a comparison is made through evaluating the within and between-class species variability for the original, the first derivative and second derivative spectra. For each, the experiment was conducted (i) over the entire electromagnetic ... Read more
