摘要
Abstract
Within the technical framework about "multi-level remote sensing alteration information separation and extraction" the complex remote sensing alteration information extraction is transformed to the analysis of the three targets i. e. , background, interference and alteration of a remote sensing image on basis of diagnosis of the remote sensing image characteristics. The geometric structural analysis of spectral data space (also known as feature space) is apllied to the research and spatial orientation of the clustering structure of the three targets, especially for the identification and division of interference factors. By means of M value estimation of end member of multi-band remote sensing data the background-abnormal subspace is determined. Then characteristic bands for the information extraction are chosen with regression skewness curve analysis and spectral reflectance characteristics of surface features. Based on the comprehensive analysis, Crosta-based F and H factor analysis and characteristic bands chosen for the alteration information extraction we developed software to extract mineralization and alteration information in Cebu Island, Philippines from remote sensing images. Results show that the known deposits are all in theextracted anomaly areas and the extraction technology should be popularized.关键词
