This paper presents an improved tracking based method for retinal vessel segmentation that uses blood vessel morphology to adapt the tracking parameters. The method includes branching detection and avoidance methods. A bi-level threshold method, based on l ...
Automated tracking of objects through a sequence of images has remained one of the difficult problems in computer vision. Numerous algorithms and techniques have been proposed for this task. Some algorithms perform well in restricted environments, such as ...
Particle filters are now established as the most popular method for visual tracking. Within this framework, it is generally assumed that the data are temporally independent given the sequence of object states. In this paper, we argue that in general the da ...
This report presents an improved tracking based method for retinal vessel segmentation that uses blood vessel morphology to adapt the tracking parameters. The method includes branching detection and avoidance methods. A bi-level threshold method, based on ...
As demand increases for positioning rescue crews, military users, and individuals with special needs, miniaturized low-power inertial measurement units (IMUs) coupled with GPS receivers and other sensors can provide accurate position in both indoor and out ...
In this paper, we present a way to track multiple maneuvering targets with varying time-frequency signatures. A particle filter is used to track targets that have constant speeds with changing heading directions. The target motion dynamics help the particl ...
This paper presents an application where an integrated GPS/IMU system is used for land survey (mounted on a van), providing a significant improvement on the efficiency of the road status monitoring process. Being initially developed for aircraft navigation ...
This paper considers the problem of routing in a wide area mobile ad-hoc network called Terminode Network. Our routing scheme is a combination of two protocols called Termin-ode Local Routing (TLR) and Terminode Remote Routing (TRR). TRR is activated when ...
The focus of this paper is routing in a wide area mo-bile ad hoc network referred to as a Terminode Network. Our routing scheme is a combination of two protocols: Terminode Local Routing (TLR) and Terminode Remote Routing (TRR). TRR is used for rem ote des ...
This article discusses the problem of GPS integration with dead-reckoning sensors for land vehicle navigation applications. The discussion follows the results of the development and implementation of navigation systems for management of fleets, one of them ...
