一种结合CEM的高光谱遥感影像目标检测算法
Target Detection Algorithm of Hyperspectral Remote Sensing Imagery Combined with CEM
摘要
Abstract
A target detection algorithm based on CEM (Constrained Energy Minimum) is proposed.The virtual dimensionality algorithm is employed to effectively estimate the number of endmembers,and the interested endmembers are extracted from hyperspectral images.MNF (Maximum Noise Fraction) is introduced for the dimensionality reduction of original images.Based on the results of virtual dimensionality,the reasonable number of principle component is selected.According to the target endmembers,an improved CEM detector is used for target detection.Experimental results show that the proposed algorithm provides better performance of target detection for hyperspectral images.关键词
