Spectral features recognition based on data mining algorithms

In order to discover those significant spectral features that are of effectiveness to target identification, some Data Mining algorithms were used to the data sets from USGS spectral library and OMIS hyperspectral remote sensing image. The candidate feature sets were generated by traditional spectral feature extraction approaches at first, and then clustering, statistical analysis and decision tree were used to characterized feature recognition and target identification model design. Derivative spectrum has the superiority of enhancing the characteristic spectral features in contrast with other algorithms. The recognition decision tree based on the knowledge and rules can identify and discriminate targets using the discovered spectral features. The experiment showed that the proposed characterized spectral features recognition approach based on Data Mining algorithm was suitable to hyperspectral remote sensing information processing.
