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

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