| Abstract: | Experimental Studies about Methods on Optimal Bands Selection ofHyperspectral Remote Sensing DatasetsLIU Jian-ping, ZAHO Ying-shi, SUN Shu-ling(The Graduate School,University of Science&;Technology of China.Beijing100039China)Abstract:The intrinsical relationships of the“entropy”methods on optimal bands selection in multispectralremote sensing data interpretation are analysed,and limitations of using these methods in hyperspectral re-mote sensing data interpretation explained.The optimal bands selection principles and methods based onthe classes distinguishability are put forward.The validity,accuracy,limitations and computational com-plexity of the processing methods concerned are illustrated throuh experiments.Key words:Hyperspectral remote sensing data, Optimal bands selection, Integrated entropy, Distin-guishability |
