However, the limitation of Gaussian random variables on its computational complexity or sparsity affects the efficiency and accuracy. This paper proposes a novel approach for the optimization of measurement matrix in compressive sensing (CS) theory for hyperspectral unmixing. Firstly, a new Toeplitz-structured chaotic measurement matrix (TSCMM) is formed by pseudo-random chaotic elements, which can be implemented by a simple hardware; secondly, rank revealing QR factorization with eigenvalue decomposition is presented to speed up the measurement time; finally, orthogonal gradient descent method for measurement matrix optimization is used to achieve optimal incoherence. Experimental results demonstrate that the proposed approach can lead to better CS reconstruction performance with low extra computational cost in hyperspectral unmixing.<\/jats:p>","DOI":"10.1155\/2017\/8471024","type":"journal-article","created":{"date-parts":[[2017,7,3]],"date-time":"2017-07-03T21:03:07Z","timestamp":1499115787000},"page":"1-13","source":"Crossref","is-referenced-by-count":3,"title":["A Novel Measurement Matrix Optimization Approach for Hyperspectral Unmixing"],"prefix":"10.1155","volume":"2017","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1818-6766","authenticated-orcid":true,"given":"Su","family":"Xu","sequence":"first","affiliation":[{"name":"College of Computer Science and Information Engineering, Chongqing Technology and Business University, Chongqing 400067, China"},{"name":"Chongqing Engineering Laboratory for Detection, Control and Integrated System, Chongqing Technology and Business University, Chongqing 400067, China"}]},{"given":"Xiping","family":"He","sequence":"additional","affiliation":[{"name":"College of Computer Science and Information Engineering, Chongqing Technology and Business University, Chongqing 400067, China"},{"name":"Chongqing Engineering Laboratory for Detection, Control and Integrated System, Chongqing Technology and Business University, Chongqing 400067, China"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.2006.871582"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.2005.862083"},{"issue":"1","key":"3","doi-asserted-by":"crossref","first-page":"19","DOI":"10.5573\/IEIESPC.2014.3.1.19","volume":"3","year":"2014","journal-title":"Transactions on Smart Processing & Computing"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2011.2165289"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1186\/1687-1499-2013-161"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2007.900760"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1002\/mrm.21391"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2009.2022459"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2009.2032889"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2006.881199"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1155\/2010\/560349"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1016\/j.sigpro.2011.10.012"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1007\/s00034-013-9706-0"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2013.2253776"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1049\/cje.2016.01.013"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2014.2348796"},{"key":"33","first-page":"1","volume":"8","year":"2014","journal-title":"International Journal of Distributed Sensor Networks"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4612-3486-9"},{"key":"28","doi-asserted-by":"publisher","DOI":"10.1007\/s00365-007-9003-x"},{"key":"32","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.2011.2173241"}],"container-title":["Journal of Control Science and Engineering"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jcse\/2017\/8471024.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jcse\/2017\/8471024.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jcse\/2017\/8471024.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,6,21]],"date-time":"2025-06-21T00:46:09Z","timestamp":1750466769000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/jcse\/2017\/8471024\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":20,"alternative-id":["8471024","8471024"],"URL":"https:\/\/doi.org\/10.1155\/2017\/8471024","relation":{},"ISSN":["1687-5249","1687-5257"],"issn-type":[{"type":"print","value":"1687-5249"},{"type":"electronic","value":"1687-5257"}],"subject":[],"published":{"date-parts":[[2017]]}}}
