Myocardium tracking via matching distributions
International Journal of Computer Assisted Radiology and Surgery, 2008The goal of this study is to investigate automatic myocardium tracking in cardiac Magnetic Resonance (MR) sequences using global distribution matching via level-set curve evolution. Rather than relying on the pixelwise information as in existing approaches, distribution matching compares intensity distributions, and consequently, is well-suited to the ...

Active Contours for Tracking Distributions
IEEE Transactions on Image Processing, 2004A new approach to tracking using active contours is presented. The class of objects to be tracked is assumed to be characterized by a probability distribution over some variable, such as intensity, color, or texture. The goal of the algorithm is to find the region within the current image, such that the sample distribution of the interior of the region

Event-Triggered Distributed Multitarget Tracking
IEEE Transactions on Signal and Information Processing over Networks, 2019This paper focuses on reducing communication bandwidth and, consequently, energy consumption in the context of distributed multitarget tracking over a peer-to-peer sensor network. A consensus cardinalized probability hypothesis density (CCPHD) filter with event-triggered communication is developed by enforcing each node to broadcast its local ...

Distributed Tracking in Distributed Sensor Networks
1986 American Control Conference, 1986A distributed sensor network (DSN) consists of a set of processing nodes collecting data from sensors. When the nodes communicate, each node fuses the information received from other nodes with the local information to update its estimate on the state of the world.
