Abstract

This paper presents a novel classification method of hyperspectral image(HSI) based on EMAPs and SMLR. Firstly, we adopt EMAPs(Extended Morphological multi-Attribute Profiles) algorithm to extract the spatial information of HSI efficiently, and combine the spectral information to form spatial-spectral features fusion model. EMAPs can replace simple structural elements with multiple attributes structure and cascade them to obtain attributes feature of multiple structures. Then we utilize SMLR(Sparse Multinomial Logistic Regression) for HSI classification. SMLR is applicable to high-dimensional and large data sets. A multiclass classifier based on MLR is adopted, and a fast algorithm is used to learn a sparse multiclass classifier. Compared with other methods in HSI experiments, our method provides an excellent result.
