      An AM-FM model for motion estimation in atherosclerotic plaque videos 

      Murray, V.; Murillo, S. E.; Pattichis, Marios S.; Loizou, Christos P.; Pattichis, Constantinos S.; Kyriacou, Efthyvoulos C.; Nicolaïdes, Andrew N. (2007)
      We present new multidimensional Amplitude-Modulation Frequency-Modulation (AM-FM) methods for motion estimation. For a single AM-FM component we show that the optical flow constraint leads to separate equations for amplitude ...

      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 ...
