    • Error reduction through post processing for wireless capsule endoscope video 

      Floor, Pål Anders; Farup, Ivar; Pedersen, Marius; Hovde, Øistein (Peer reviewed; Journal article, 2020)
      The wireless capsule endoscope (WCE) is a pill-sized device taking images, which are transmitting to an on-body receiver, while traveling through the digestive system. Since image data is transmitted through the human body, ...
    • Evaluating clinical diversity and plausibility of synthetic capsule endoscopic images 

      Vats, Anuja; Pedersen, Marius; Mohammed, Ahmed Kedir; Hovde, Øistein (Peer reviewed; Journal article, 2023)
      Wireless Capsule Endoscopy (WCE) is being increasingly used as an alternative imaging modality for complete and non-invasive screening of the gastrointestinal tract. Although this is advantageous in reducing unnecessary ...
    • The Importance Of Skip Connections In Encoder-Decoder Architectures For Colorectal Polyp Detection 

      Mulliqi, Nita; Yildirim Yayilgan, Sule; Mohammed, Ahmed Kedir; Ahmedi, Lule; Wang, Hao; Elezaj, Ogerta; Hovde, Øistein (Chapter, 2020)
      Accurate polyp detection during the colonoscopy procedure impacts colorectal cancer prevention and early detection. In this paper, we investigate the influence of skip connections as the main component of encoder-decoder ...
    • Learning More for Free-A Multi Task Learning Approach for Improved Pathology Classification in Capsule Endoscopy 

      Vats, Anuja; Pedersen, Marius; Mohammed, Ahmed Kedir; Hovde, Øistein (Chapter, 2021)
      The progress in Computer Aided Diagnosis (CADx) of Wireless Capsule Endoscopy (WCE) is thwarted by the lack of data. The inadequacy in richly representative healthy and abnormal conditions results in isolated analyses of ...
    • PS-DeVCEM: Pathology-sensitive deep learning model for video capsule endoscopy based on weakly labeled data 

      Mohammed, Ahmed Kedir; Farup, Ivar; Pedersen, Marius; Yildirim Yayilgan, Sule; Hovde, Øistein (Peer reviewed; Journal article, 2020)
      We propose a novel pathology-sensitive deep learning model (PS-DeVCEM) for frame-level anomaly detection and multi-label classification of different colon diseases in video capsule endoscopy (VCE) data. Our proposed model ...
    • Sparse coded handcrafted and deep features for colon capsule video summarization 

      Mohammed, Ahmed Kedir; Yildirim, Sule; Pedersen, Marius; Hovde, Øistein; Alaya Cheikh, Faouzi (Journal article, 2017)
      Capsule endoscopy, which uses a wireless camera to take images of the digestive track, is emerging as an alternative to traditional wired colonoscopy. A single examination produces a sequence of approximately 50,000 frames. ...
