英文摘要	in order to further improve the operation speed and reduce the false alarm rate of the unsupervised detection method for small targets in hyperspectral remote sensing images, a detection method based on the projection pursuit (pp) optimized by improved artificial bee colony (abc) optimization algorithm and k;nearest neighbor (knn) is proposed in this paper. firstly, the kernel principal component analysis (kpca) method is adopted to perform the dimension reduction of the original hyperspectral remote sensing images. then, the method jointly defining the kurtosis and skewness according to the neighborhood pixels is proposed, the combination of the kurtosis and skewness is taken as the projection index. the improved artificial bee colony algorithm is taken as the optimization algorithm. the projection pursuit is used to obtain the projection images layer by layer from the low dimensional hyperspectral remote sensing images, and the small targets are extracted according to the histogram of these projection images. finally, the linear discriminant analysis (lda) is used to extract the features of the pixels, and the weighted k;nearest neighbor method is used to purify the preliminary detection results of the small targets. a large number of experiment results show that compared with the rx method, independent component analysis (ica) method and the projection pursuit method based on chaotic particle swarm optimization (cpso), the proposed method not only can detect the small targets in hyperspectral remote sensing image accurately, but also has faster operation speed. © 2016, science press. all right reserved.
