      Despeckle filtering for multiscale amplitude-modulation frequency-modulation (AM-FM) texture analysis of ultrasound images of the intima-media complex 

      Loizou, Christos P.; Murray, V.; Pattichis, Marios S.; Pantzaris, Marios C.; Nicolaïdes, Andrew N.; Pattichis, Constantinos S. (2014)
      The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of cardiovascular disease (CVD). Typically, the IMT grows with age and this is used as a sign of increased risk of ...

      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 ...
