Sequential Projection Pursuit of Hyperspectral Imagery Feature Extraction

ZHANG Li~(1,2),GONG Dan-chao~1,HU Hai-yan~1 (1.Xi'an Research Institute of Surveying and Mapping,Xi'an 710054,China; 2.Institute of Surveying and Mapping,Information Engineering University,Zhengzhou 450052,China)  
An efficient processing method is necessary for feature extraction of hyperspectral imagery which involvs high dimension data.In order to increase the efficiency,an improved method of sequential projection pursuit was adopted to hyperspectral images for information extraction by applying the theory and algorithm of projection pursuit.The implementing process of the method of sequential projection pursuit was focused on and the experiment on classification of hyperspectral image has been carried through.The experiment showed that the method could meet the precision of classification and improve the efficiency of the data processing.
