In this work, we propose a novel segmentation method for lung segmentation, containing two subnetworks, where few manually delineated points are used as the approximate initialization. The first one is a preprocessing subnetwork based on a deep learning model (i.e. Deep Belief Network and K-Nearest Neighbor). The second one is a refinement subnetwork, designed to make the preprocessed result to be optimized by combining an improved principal curve method and a machine learning method. To prove the performance of the proposed method, several public datasets were evaluated with Dice Similarity Coefficient (DSC), overlap score (\u03a9), Sensitivity (Sen), Positive Predictive Value (PPV), global Error (E) and execution time (t). Compared with state-of-the-art methods, our method reaches superior segmentation performance.<\/jats:p>","DOI":"10.1093\/comjnl\/bxaa148","type":"journal-article","created":{"date-parts":[[2020,11,18]],"date-time":"2020-11-18T12:18:59Z","timestamp":1605701939000},"page":"1107-1128","source":"Crossref","is-referenced-by-count":24,"title":["Deep Belief Network and Closed Polygonal Line for Lung Segmentation in Chest Radiographs"],"prefix":"10.1093","volume":"65","author":[{"given":"Tao","family":"Peng","sequence":"first","affiliation":[{"name":"School of Computer Science & Technology, Soochow University, No. 1 Shizi Road, Suzhou, Jiangsu 215006, China"},{"name":"Department of Radiation Oncology, University of Texas Southwestern Medical Center, 2280 Inwood Road, Dallas, TX 75235, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas Canhao","family":"Xu","sequence":"additional","affiliation":[{"name":"Division of Science and Technology, Beijing Normal University (BNU) and Hong Kong Baptist University (HKBU) United International College, No. 2000 Jintong Road, Tangjiawan, Zhuhai, Guangdong 519087, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yihuai","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Computer Science & Technology, Soochow University, No. 1 Shizi Road, Suzhou, Jiangsu 215006, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fanzhang","family":"Li","sequence":"additional","affiliation":[{"name":"School of Computer Science & Technology, Soochow University, No. 1 Shizi Road, Suzhou, Jiangsu 215006, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2020,12,10]]},"reference":[{"key":"2022051812594997900_ref1","doi-asserted-by":"crossref","first-page":"185","DOI":"10.1049\/iet-cvi.2009.0141","article-title":"Lung segmentation in chest radio-graphs by fusing shape information in iterative thresholding","volume":"5","author":"Dawoud","year":"2011","journal-title":"IET.
