Lung Segmentation in Chest Radiographs Using Anatomical Atlases With Nonrigid Registration
Sema Candemir,Stefan Jaeger,Kannappan Palaniappan,Jonathan P. Musco,R. Singh,Zhiyun Xue,Alexandros Karargyris,Sameer Antani,George R. Thoma,Clement J. McDonald +9 more
TL;DR: A nonrigid registration-driven robust lung segmentation method using image retrieval-based patient specific adaptive lung models that detects lung boundaries, surpassing state-of-the-art performance is presented.
Journal ArticleDOI
Automatic Tuberculosis Screening Using Chest Radiographs
Stefan Jaeger,Alexandros Karargyris,Sema Candemir,Les R. Folio,Jenifer Siegelman,Fiona M. Callaghan,Zhiyun Xue,Kannappan Palaniappan,R. Singh,Sameer Antani,George R. Thoma,Yi-Xiang J. Wang,Pu-Xuan Lu,Clement J. McDonald +13 more
TL;DR: The proposed computer-aided diagnostic system for TB screening, which is ready for field deployment, achieves a performance that approaches the performance of human experts.
Journal ArticleDOI
Small-bowel capsule endoscopy: A ten-point contemporary review
TL;DR: There is still a lot of debate around the exact reasons of SBCE poor performance in various small-bowel segments, but it is worth to remember that the capsule progress is non-steerable, hence more rapid in the proximal than in lower segments of the small-Bowel.
Journal ArticleDOI
Detection of Small Bowel Polyps and Ulcers in Wireless Capsule Endoscopy Videos
TL;DR: A novel synergistic methodology for automatically discovering polyps (protrusions) and perforated ulcers in WCE video frames is proposed.
Proceedings ArticleDOI
Semi-supervised learning with generative adversarial networks for chest X-ray classification with ability of data domain adaptation
TL;DR: For cardiac abnormality classification in chest X-rays, it is demonstrated that an order of magnitude less data is required with semi-supervised learning generative adversarial networks than with conventional supervised learning convolutional neural networks.
