Multiscale Vessel Tracking

IEEE Transactions on Medical Imaging, 2004
A method is presented that uses a vectorial multiscale feature image for wave front propagation between two or more user defined points to retrieve the central axis of tubular objects in digital images. Its implicit scale selection mechanism makes the method more robust to overlap and to the presence of adjacent structures than conventional techniques ...

4D vessel segmentation and tracking in Ultrasound

2012 19th IEEE International Conference on Image Processing, 2012
In this paper we describe a fast method to segment and track a vessel of interest in 4D (i.e. 3D + time) Ultrasound images. An initial 2D seed is used to initialize a single spatial Kalman-Filter tracker which tracks the vessel center-line in 3D. The 3D vessel is then segmented using a fast area weighted active contour method.

Vessel track summarization by viewpoint selection

Electro-Optical and Infrared Systems: Technology and Applications XVI, 2019
For military operations, the availability of high-quality imaging information from Electro-Optical / Infrared (EO/IR) sensors is of vital importance. This information can be used for timely detection and identification of threatening vessels in an environment with a large amount of neutral vessels.

Sliding-Mode Tracking Control of Surface Vessels

IEEE Transactions on Industrial Electronics, 2008
A sliding-mode control law is presented and experimentally implemented for trajectory tracking of underactuated autonomous surface vessels. The control law is developed by introducing a first-order sliding surface in terms of surge tracking errors and a second-order surface in terms of lateral motion tracking errors.

A method of vessel tracking for vessel diameter measurement on retinal images

Proceedings 2001 International Conference on Image Processing (Cat. No.01CH37205), 2002
A method of vessel tracking has been developed for quantification of vessel diameters of retinal images. This method utilises twin Gaussian functions to model the distribution of grey level over a vessel cross section. The diameter of the vessel at the cross section can then be calculated using the functions.
