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 ...

Atherosclerotic plaque motion analysis from ultrasound videos
(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 ...

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 ...

Optimal wavelength allocation and flow assignment in multiwavelength optical networks
(2001)Automatically Switched Optical Networks (ASON) require a control strategy that determines the optimal distribution of flows over different wavelengths. Such strategy will increase the profit, by allowing service providers ...
