| Abstract: | In the present study,based on the leaf-level hyperspectral data of MaoZhu,LeiZhu and XiaoShunZhu,We come up with two solutions to discrimination through the theory of non-parametric test and pattern recognition;the first one is that optimal discriminating band between bambusoideae species is extracted by Mann-Whitney non-parametric test,the other is that bambusoideae species is discriminated by the support vector machine.The research results showed that(1) the optimal discriminating band between MaoZhu and ... |
