      Atherosclerotic plaque motion analysis from ultrasound videos 

      Murillo, S. E.; Pattichis, Marios S.; Loizou, Christos P.; Pattichis, Constantinos S.; Kyriacou, Efthyvoulos C.; Constantinides, Anthony G.; Nicolaïdes, Andrew N. (2006)
      In this paper, we describe a collection of algorithms that are used to provide motion trajectory estimates from atherosclerotic plaque ultrasound videos. Our approach is based on the use of four different optical flow ...

      Brownian-like kinematics of ball milling for particulate structural modeling 

      Doumanidis, C. C.; Kaabi, H. A. Al; Alzaabi, A. S. M.; Gunduz, I. E.; Rebholz, Claus; Doumanidis, C. C. (2016)
      Ball milling motion has been previously studied through computationally expensive, off-line experimental video processing and numerical simulations by the discrete element method. This research establishes a more efficient ...

      Global optimization for motion estimation with applications to ultrasound videos of carotid artery plaques 

      Murillo, S.; Pattichis, Marios S.; Soliz, P.; Barriga, S.; Loizou, Christos P.; Pattichis, Constantinos S. (2010)
      Motion estimation from digital video is an ill-posed problem that requires a regularization approach. Regularization introduces a smoothness constraint that can reduce the resolution of the velocity estimates. The problem ...

      LMA-based motion retrieval for folk dance cultural heritage 

      Aristidou, Andreas; Stavrakis, E.; Chrysanthou, Yiorgos L. (2014)
      Motion capture (mocap) technology is an efficient method for digitizing art-performances, and it is becoming a popular method for the preservation and dissemination of dances. However, stylistic variations of human motion ...

      M-mode state based identification in ultrasound videos of the atherosclerotic carotid plaque 

      Loizou, Christos P.; Pantzaris, Marios C.; Pattichis, Constantinos S.; Kyriacou, Efthyvoulos C. (2010)
      Monitoring the wall and plaque changes in the carotid artery (CA) can provide useful information for the assessment of the atherosclerotic disease. Using a motion mode (M-mode) image, detailed information may be obtained ...

      Measurement of motion of carotid bifurcation plaques 

      Nasrabadi, H.; Pattichis, Marios S.; Nicolaïdes, Andrew N.; Griffin, Maura B.; Makris, Gregory C.; Fisher, P.; Kyriacou, Efthyvoulos C.; Pattichis, Constantinos S. (2012)
      Video loops of B-mode ultrasound images of 35 carotid bifurcation plaques were obtained (4 symptomatic and 31 asymptomatic) from patients with carotid bifurcation atherosclerosis. Video loops were classified visually as ...

      Multi-scale AM-FM motion analysis of ultrasound videos of carotid artery plaques 

      Murillo, S.; Murray, V.; Loizou, Christos P.; Pattichis, Constantinos S.; Pattichis, Marios S.; Barriga, E. S. (2012)
      An estimated 82 million American adults have one or more type of cardiovascular diseases (CVD). CVD is the leading cause of death (1 of every 3 deaths) in the United States. When considered separately from other CVDs, ...

      A review of noninvasive ultrasound image processing methods in the analysis of carotid plaque morphology for the assessment of stroke risk 

      Kyriacou, Efthyvoulos C.; Pattichis, Constantinos S.; Pattichis, Marios S.; Loizou, Christos P.; Christodoulou, Chris C.; Kakkos, Stavros K.; Nicolaïdes, Andrew N. (2010)
      Noninvasive ultrasound imaging of carotid plaques allows for the development of plaque-image analysis methods associated with the risk of stroke. This paper presents several plaque-image analysis methods that have been ...

      Upper limb assessment of people with multiple sclerosis with the use of a haptic nine hole peg-board test 

      Xydas, E. G.; Louca, Loucas S. (Affiliation: Department of Mechanical and Manufacturing Engineering, University of Cyprus, CyprusCorrespondence Address: Xydas, E. G.Department of Mechanical and Manufacturing Engineering, University of CyprusCyprus, 2009)
      In this work, a nine-hole peg-board test (NHPT) arrangement is implemented in a Virtual Environment with the use of a Haptic Interface that has the form of a small robotic arm. The Haptic NHPT is used as a mean for ...
