      An adaptive multiscale AM-FM texture analysis system with application to hysteroscopy imaging 

      Constantinou, Ioannis P.; Pattichis, Marios S.; Tanos, Vasilios; Neofytou, Marios S.; Pattichis, Constantinos S. (2012)
      The use of multiscale AM-FM analysis systems has been recently demonstrated in a variety of applications in medical image analysis. In all of these applications, a fixed filter-bank is used as a preprocessing step for ...

      Despeckle filtering in ultrasound video of the common carotid artery 

      Loizou, Christos P.; Kasparis, Takis; Christodoulides, Paul; Theofanous, Charoula; Pantzaris, Marios C.; Kyriacou, Efthyvoulos C.; Pattichis, Constantinos S. (2012)
      Noise reduction is essential for increasing the visual quality or as a preprocessing step for further automated analysis in video sequences and video coding. The objective of this work was to investigate four different ...

      Fullsphere irradiance factorization for real-time all-frequency illumination for dynamic scenes 

      Michael, D.; Chrysanthou, Yiorgos L. (2010)
      Computation of illumination with soft-shadows from all-frequency environment maps, is a computationally expensive process. Use of pre-computation add the limitation that receiver's geometry must be known in advance, since ...

      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 ...
