【Abstract】 The observed hyperspectral data is a superposition of a variety of signal informations and include instrument noise and environmental disturbance, which will contaminate the target information of observed data. Th erefore, before analysing the hyperspectral data, the processing of observed hyp erspectral data is needed to remove the interference of non-target information. In this paper, three filtering methods for the observed hyperspectral data are introduced, and the analysis of the application effect is also made.更多还原
