      Biologically inspired region of interest selection for low bit-rate video coding 

      Tsapatsoulis, Nicolas; Pattichis, Constantinos S.; Rapantzikos, K. (2006)
      A variety of approaches have been proposed in the literature for Region-Of-Interest (ROI) estimation. In most of them the ROI definition is highly subjective, i.e., lacks scientific evidence in supporting the claim that ...

      An effective ultrasound video communication system using despeckle filtering and HEVC 

      Panayides, Andreas S.; Pattichis, Marios S.; Loizou, Christos P.; Pantzaris, Marios C.; Constantinides, Anthony G.; Pattichis, Constantinos S. (2015)
      The recent emergence of the high-efficiency video coding (HEVC) standard promises to deliver significant bitrate savings over current and prior video compression standards, while also supporting higher resolutions that can ...

      An embedded saliency map estimator scheme: Application to video encoding 

      Tsapatsoulis, Nicolas; Rapantzikos, K.; Pattichis, Constantinos S. (2007)
      In this paper we propose a novel saliency-based computational model for visual attention. This model processes both top-down (goal directed) and bottom-up information. Processing in the top-down channel creates the so ...

      High efficiency video coding for ultrasound video communication in m-health systems 

      Panayides, Andreas S.; Antoniou, Zinonas C.; Pattichis, Marios S.; Pattichis, Constantinos S.; Constantinides, Anthony G. (2012)
      Emerging high efficiency video compression methods and wider availability of wireless network infrastructure will significantly advance existing m-health applications. For medical video communications, the emerging video ...

      Image-based crowd rendering 

      Tecchia, F.; Loscos, C.; Chrysanthou, Yiorgos L. (2002)
      Rendering crowded scenes with thousands of different animated virtual people in real time is challenging. An image-based rendering approach for displaying multiple avatars is proposed. The system allows real-time rendering ...

      An overview of recent end-to-end wireless medical video telemedicine systems using 3G 

      Panayides, Andreas S.; Pattichis, Marios S.; Pattichis, Constantinos S.; Schizas, Christos N.; Spanias, Andreas S.; Kyriacou, Efthyvoulos C. (2010)
      Advances in video compression, network technologies, and computer technologies have contributed to the rapid growth of mobile health (m-health) systems and services. Wide deployment of such systems and services is expected ...

      Robust and efficient ultrasound video coding in noisy channels using H.264 

      Panayides, Andreas S.; Pattichis, Marios S.; Pattichis, Constantinos S.; Loizou, Christos P.; Pantzaris, Marios C.; Pitsillides, Andreas (2009)
      In this paper we define diagnostic Regions of Interest (ROIs) for carotid ultrasound medical video, which we then use as input for Flexible Macroblock Ordering (FMO) slice encoding. We extend the FMO concept by enabling ...

      Wireless medical ultrasound video transmission through noisy channels 

      Panayides, Andreas S.; Pattichis, Marios S.; Pattichis, Constantinos S. (2008)
      Recent advances in video compression such as the current state-of-the-art H.264/AVC standard in conjunction with increasingly available bitrate through new technologies like 3G, and WiMax have brought mobile health (m-Health) ...
