Vessel Tracking Algorithms in Ultrasound Imaging

2008 2nd International Conference on Bioinformatics and Biomedical Engineering, 2008
Doctors usually observe patients' ultrasound vessel images to obtain clinical information about vascular diseases, and sometimes they want to measure the vessel diameter from the images. The aim of this paper is to provide a convenient method to measure the vessel diameter from the images.

Nonlinear tracking of underactuated surface vessels

Proceedings of 35th IEEE Conference on Decision and Control, 2002
A control law for tracking of underactuated surface vessels is presented. Optimal trajectories for surface vessels are given as combinations of arcs of circles and line segments. It is shown how optimal trajectories can be made smooth by a technique called splines, and how these trajectories can be stabilized by backstepping. The control law depends on

Tracking control of an underactuated surface vessel

Proceedings of the 37th IEEE Conference on Decision and Control (Cat. No.98CH36171), 2002
We consider tracking control of a surface vessel with only two control inputs. The surface vessel model has certain similarities with chained form systems, but cannot be transformed to chained form. In particular, the model has a drift vector field as opposed to the drift-free chained form systems.

Vessel Tracking and Movement Radius Notification

2009
The tracking of vessels can be useful for any type of vessel renting, especially if vessel value is high and there is a possibility of vessel theft. In this work we present a sea vessel tracking web service which utilizes previously developed prediction system modified for this purpose.
