SSC is designed to represent data as an union of affine subspaces, while it cannot capture the latent structure of the given data. In Mosers theory, the distribution can represent the intrinsic structure efficiently. Hence, we propose a novel approach called spatial distribution preserving-based sparse subspace clustering (SSC-SDP) in this paper for HSI data, which can help sparse representation preserve the underlying manifold structure. Specifically, the density constraint is added by minimizing the inconsistency of the densities estimated in the HSI data and the corresponding sparse coefficient matrix. In addition, we incorporate spatial information into the density estimation of the original data, and the optimization solution based on alternating direction method of multipliers (ADMM) is devised. Three HSI data sets are conducted to evaluate the performance of our SSC-SDP compared with other state-of-art algorithms. <\/jats:p>","DOI":"10.1142\/s0219691319400101","type":"journal-article","created":{"date-parts":[[2018,5,22]],"date-time":"2018-05-22T09:00:51Z","timestamp":1526979651000},"page":"1940010","source":"Crossref","is-referenced-by-count":3,"title":["Spatial distribution preserving-based sparse subspace clustering for hyperspectral image"],"prefix":"10.1142","volume":"17","author":[{"given":"Yiyang","family":"Ding","sequence":"first","affiliation":[{"name":"College of Computer Science, Chongqing University, Chongqing 400030, P.
