2. 6. Conjugate priors for Bayesian object tracking

   Author : Yuxuan Xia; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bayesian estimation; object tracking; multi-object smoothing; backward simulation; automotive radar; extended object; conjugate prior; random finite sets; multi-object tracking; sets of trajectories.;

   Abstract : Object tracking refers to the problem of using noisy sensor measurements to determine the location and characteristics of objects of interest in clutter. Nowadays, object tracking has found applications in numerous research venues as well as application areas, including air traffic control, maritime navigation, remote sensing, intelligent video surveillance, and more recently environmental perception, which is a key enabling technology in autonomous vehicles.

4. 7. Counting and Tracking : Development and Use of New Methods for Detailed Analysis of Thrombus Formation

   Author : Kjersti Tunströmer; Tomas Lindahl; Lars Faxälv; Nathaniel D Robinson; Judith Cosemans; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Blood platelets are a part of the complex system called haemostasis aimed at ensuring our blood’s continuous transport of oxygen and nutrients throughout the body. The transport is ensured by limiting blood loss due to vessel injury and in this process, the platelets form a plug in the damaged area, reinforced by the formation of fibrin. READ MORE

5. 8. Position Estimation and Tracking in Colloidal Particle Microscopy

   Author : Mats Kvarnström; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; censored regression; colloidal chemistry; depth estimation; diffusion coefficient; nonparametric function estimation; position estimation; rotational symmetry; tracking; template matching; video microscopy; rotational symmetry;

   Abstract : This thesis presents methods for estimating the locations (including depth) of spherical colloidal particles in images recorded in video microscopy. Understanding the behavior of colloidal interactions and diffusion is of crucial importance in a vast number of areas. READ MORE

6. 9. Multiple Model Filtering and Data Association with Application to Ground Target Tracking

   Author : Daniel Svensson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiple model filtering; semi-Markov processes; multi-target tracking; FISST; state estimation; IMM; performance evaluation; OSPA; PHD; ground target tracking; Kalman filtering; target tracking; CPHD; MHT; random finite sets;

   Abstract : This thesis is concerned with two central parts of a tracking system, namely multiple-model filtering and data association. Multiple models are introduced to provide accurate filtering, whereas data association deals with the unknown origin of the received measurements. READ MORE

7. 10. Nonparametric Message Passing Methods for Cooperative Localization and Tracking

   Author : Vladimir Savic; Santiago Zazo; Spain Technical University of Madrid; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooperative localization; tracking; wireless sensor networks; message passing; particle filtering; belief propagation; RFID;

   Abstract : The objective of this thesis is the development of cooperative localization and tracking algorithms using nonparametric message passing techniques. In contrast to the most well-known techniques, the goal is to estimate the posterior probability density function (PDF) of the position of each sensor. READ MORE
