This paper presents a multibiometric system that integrates the iris and face features based on the fusion at the feature level. The proposed multibiometric system has three novelties as compared to the previous works. First, distance regularized level-set evolution (DRLSE) technique is utilized to localize the iris and pupil boundary from an iris image. The DRLSE maintains the regularity of the level set function intrinsically during the curve evolution process and increases the numerical accuracy substantially. The proposed iris localization scheme is robust against poor localization and weak iris\/sclera boundaries. Second, a modified local binary pattern (MLBP), which combines both the sign and magnitude features for the improvement of recognition performance, is applied. Third, to select the optimal subset of features from the fused feature vector, a feature subset selection scheme based on random forest (RF) is proposed. To evaluate the performance of the proposed scheme, the facial images of Yale Extended B Face database are fused with the iris images of CASIA V4 interval dataset to construct an iris\u2013face multimodal biometric dataset. The experimental results indicate that the proposed multimodal biometrics system is more reliable and robust than the unimodal biometric scheme. <\/jats:p>","DOI":"10.1142\/s0219467814500132","type":"journal-article","created":{"date-parts":[[2014,8,25]],"date-time":"2014-08-25T05:38:50Z","timestamp":1408945130000},"page":"1450013","source":"Crossref","is-referenced-by-count":5,"title":["Multibiometric System Using Level Set, Modified LBP and Random Forest"],"prefix":"10.1142","volume":"14","author":[{"given":"Kaushik","family":"Roy","sequence":"first","affiliation":[{"name":"Department of Computer Science, North Carolina A&T State University, Greensboro, NC, USA"}]},{"given":"Brian","family":"O'Connor","sequence":"additional","affiliation":[{"name":"Department of Computer Science, North Carolina A&T State University, Greensboro, NC, USA"}]},{"given":"Foysal","family":"Ahmad","sequence":"additional","affiliation":[{"name":"Department of Computer Science, North Carolina A&T State University, Greensboro, NC, USA"}]},{"given":"Mohamed S.","family":"Kamel","sequence":"additional","affiliation":[{"name":"Centre for Pattern Analysis & Machine Intelligence, University of Waterloo, ON, Canada"}]}],"member":"219","published-online":{"date-parts":[[2014,8,25]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2011.02.155"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1109\/TCSVT.2003.818350"},{"key":"rf6","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-74549-5_19"},{"key":"rf8","doi-asserted-by":"publisher","DOI":"10.1007\/11608288_76"},{"key":"rf14","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2010.2069690"},{"key":"rf15","doi-asserted-by":"publisher","DOI":"10.1023\/A:1010933404324"},{"key":"rf17","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2010.2044957"},{"key":"rf19","doi-asserted-by":"publisher","DOI":"10.1016\/j.optlaseng.2010.09.011"},{"key":"rf20","doi-asserted-by":"publisher","DOI":"10.1016\/j.engappai.2010.06.014"},{"key":"rf22","doi-asserted-by":"publisher","DOI":"10.1109\/TIFS.2009.2033225"},{"key":"rf23","doi-asserted-by":"publisher","DOI":"10.1109\/TPAMI.2002.1017623"},{"key":"rf27","doi-asserted-by":"publisher","DOI":"10.1007\/s10032-009-0107-7"}],"container-title":["International Journal of Image and Graphics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0219467814500132","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,6]],"date-time":"2019-08-06T15:12:37Z","timestamp":1565104357000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0219467814500132"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,7]]},"references-count":12,"journal-issue":{"issue":"03","published-online":{"date-parts":[[2014,8,25]]},"published-print":{"date-parts":[[2014,7]]}},"alternative-id":["10.1142\/S0219467814500132"],"URL":"https:\/\/doi.org\/10.1142\/s0219467814500132","relation":{},"ISSN":["0219-4678","1793-6756"],"issn-type":[{"value":"0219-4678","type":"print"},{"value":"1793-6756","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,7]]}}}
