The tracking number of an algebra
American Journal of Mathematics, 2005We introduce the technique of tracking numbers of graded algebras and modules. It is a modified version of the first Chern class of its free resolution relative to any of its standard Noether normalizations. Several estimations are obtained which are used to bound the length of chains of algebras occurring in the construction of the integral closure ...

An approach to SAR tomography with limited number of tracks
2009 IEEE International Geoscience and Remote Sensing Symposium, 2009In SAR tomography, the available information in the height direction is limited by the number of different tracks that can be acquired in practice. To counterbalance this limitation, electromagnetic scattering models, properly exploiting the available a priori information, should be used, the “few” possible acquisitions should be accurately selected ...

Tracking a Variable Number of Objects
2020Bayesian estimators of a time-varying number of objects and their states are developed. The estimators are based on object superposition, a fundamental concept in finite point processes that is adapted to model multiobject state. The concept of superposition is introduced carefully step by step, starting with its application to the JPDA filter for a ...

Tracking a Specified Number of Objects
2020The joint probabilistic data association (JPDA) and joint integrated probabilistic data association (JIPDA) filters are presented and derived from the AC point of view. JPDA stipulates the number of objects to be tracked, so it requires an external track management system to initiate and terminate object tracks.

On Self-Localization and Tracking with an Unknown Number of Targets
2018 52nd Asilomar Conference on Signals, Systems, and Computers, 2018We propose a scalable algorithm for cooperative self-localization and multi-target tracking. Mobile agents localize themselves, and track an unknown number of targets in the presence of data-association uncertainty. We accomplish this task by modeling the probabilistic relationship between agent and target measurements alongside their state estimates ...

Particle filters for tracking an unknown number of sources
IEEE Transactions on Signal Processing, 2002This paper addresses the application of sequential importance sampling (SIS) schemes to tracking directions of arrival (DOAs) of an unknown number of sources, using a passive array of sensors. This proposed technique has significant advantages in this application, including the ability to detect a changing number of signals at arbitrary times ...

Blockchain for tracking serial numbers in money exchanges
Intelligent Systems in Accounting, Finance and Management, 2019SummaryMoney exchange is one of the most common day‐to‐day activities performed by humans in the daily market. This paper presents an approach to money tracking through a blockchain. The proposed approach consists of three main components: serial number localization, serial number recognition, and a blockchain to store all transactions and ownership ...

Variable Number of "Informative" Particles for Object Tracking
Multimedia and Expo, 2007 IEEE International Conference on, 2007Particle filter is a sequential Monte Carlo method for object tracking in a recursive Bayesian filtering framework. The efficiency and accuracy of the particle filter depends on two key factors: how many particles are used and how these particles are re-located.
