• Efficient enhancement of stereo endoscopic images based on joint wavelet decomposition and binocular combination 

      Sdiri, Bilel; Kaaniche, Mounir; Alaya Cheikh, Faouzi; Beghdadi, Azeddine; Elle, Ole Jacob (Peer reviewed; Journal article, 2019)
      The success of minimally invasive interventions and the remarkable technological and medical progress have made endoscopic image enhancement a very active research field. Due to the intrinsic endoscopic domain characteristics ...
    • Liver surface reconstruction for image guided surgery 

      Wang, Congcong; Alaya Cheikh, Faouzi; Kaaniche, Mounir; Elle, Ole Jacob (Journal article; Peer reviewed, 2018)
      In image guided surgery, stereo laparoscopes have been introduced to provide a 3D view of the organs during the laparoscopic intervention. This stereo video could possibly be used for other purposes other than simple ...
    • 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 ...
    • Variational based smoke removal in laparoscopic images 

      Wang, Congcong; Alaya Cheikh, Faouzi; Kaaniche, Mounir; Beghdadi, Azeddine; Elle, Ole Jacob (Journal article; Peer reviewed, 2018)
      Background In laparoscopic surgery, image quality can be severely degraded by surgical smoke, which not only introduces errors for the image processing algorithms (used in image guided surgery), but also reduces the ...
