      Head detection in real-world videos is a classical research problem in computer vision. Head detection in videos is challenging than in a single image due to many nuisances that are commonly observed in natural videos, ...
    • Towards a video quality assessment based framework for enhancement of laparoscopic videos 

      Khan, Zohaib Amjad; Beghdadi, Azeddine; Alaya Cheikh, Faouzi; Kaaniche, Mounir; Pelanis, Egidijus; Palomar, Rafael; Fretland, Åsmund Avdem; Edwin, Bjørn; Elle, Ole Jacob (Peer reviewed; Journal article, 2020)
      Laparoscopic videos can be affected by different distortions which may impact the performance of surgery and introduce surgical errors. In this work, we propose a framework for automatically detecting and identifying such ...
    • Use of the IQRF Technology in Internet-of-Things-Based Smart Cities 

      Bouzidi, Mohammed; Dalveren, Yaser; Alaya Cheikh, Faouzi; Derawi, Mohammad (Peer reviewed; Journal article, 2020)
      In recent years, there has been a growing interest in building smart cities based on the Internet of Things (IoT) technology. However, selecting a low-cost IoT wireless technology that enables low-power connectivity remains ...
    • Validation of stereo vision based liver surface reconstruction for image guided surgery 

      Teatini, Andrea; Wang, Congcong; Palomar, Rafael; Alaya Cheikh, Faouzi; Edwin, Bjørn; Elle, Ole Jacob (Chapter, 2018)
      Image guided surgery systems aim to provide navigation to surgeons in order to improve accuracy and safety of the procedures. Through stereo reconstruction algorithms, it is possible to generate 3D surfaces intra-operatively ...
    • Variational based smoke removal in laparoscopic images
