Abstract

Aiming at the problem of ignoring spatial features in traditional hyperspectral image classification algorithm, this paper proposed a hyperspectral image classification algorithm based on dimensionality reduction Gabor feature and decision fusion. Firstly, it intelligently grouped the adjacent and hyper correlated spectral bands by coefficient correlation matrix. Then, it extracted Gabor features in each group from the PCA projection subspace to quantify the local direction and scale features. Then, it reduced the dimensionality of these feature subspaces by preserving the locality of the decomposition of nonnegative matrices. Finally, it classified the reduced dimension features by Gaussian mixture model, and merged the classification results by decision fusion rules. Experimental results show that the proposed algorithm is superior to eight kinds of traditional and existing advanced classification algorithms.
