      Adaptive noise canceling and edge detection in images using PVM on a NOW 

      Mylonas, S. A.; Trancoso, Pedro; Trimikliniotis, Michael (IEEE, 2000)
      A method for the processing of digital images using a two-dimensional LMS adaptive filter for noise reduction and subsequent edge detection is presented. This was implemented on a Parallel Virtual Machine (PVM) consisting ...

      Ultrasound video despeckle filtering for High Efficiency Video Coding in m-health systems 

      Panayides, Andreas S.; Loizou, Christos P.; Pattichis, Marios S.; Kyriacou, Efthyvoulos C.; Shizas, C. N.; Nicolaïdes, Andrew N.; Pattichis, Constantinos S. (2013)
      Mobile-Health (m-health) medical video communication systems need to communicate ultrasound video of adequate diagnostic quality for remote diagnosis and care. In this study, we demonstrate how ultrasound video noise ...
