摘要
Abstract
Spectral unmixing of remote sensing imagery as a remote sensing classification and cartographic method has its unique advantages. In this paper, Hyperion remote sensing images of Fukang region was used, in ENVI/IDL software running environment, respectively, utilizing the hourglass algorithm method, SMACC algorithm and volume method for endmember extraction. A comparative analysis of these methods to choose the actual extraction of the end of the hourglass algorithm as the most terminal endmember had been carried out. On this basis, respectively using the fully constrained least square method and OSP algorithm for mixed-pixel decomposition, all unmixing methods had been counted and compared. The results showed that in the area, the endmember extracted from hourglass algorithms had higher accuracy, and the result of all constrained least squares was satisfied to the ground fact.关键词
