2. 16. 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

4. 17. Methods for Visually Guided Robotic Systems : Matching, Tracking and Servoing

   Author : Fredrik Larsson; Michael Felsberg; Per-Erik Forssén; Josef Bigün; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : This thesis deals with three topics; Bayesian tracking, shape matching and visual servoing. These topics are bound together by the goal of visual control of robotic systems. The work leading to this thesis was conducted within two European projects, COSPAL and DIPLECS, both with the stated goal of developing artificial cognitive systems. READ MORE

5. 18. Models for tracking in automotive safety systems

   Author : Fredrik Bengtsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; motion models; active safety; vehicle tracking; Automotive; radar detections; preventive safety;

   Abstract : This thesis treats the three main components of a tracking system: motion models, sensor models and implementation architecture. A tracking system utilizes models to extract as much information as possible from a set of sensors, with the purpose of estimating the state of a dynamic system. READ MORE

6. 19. Tracking Information Flows in Interactive and Object-Oriented Programs

   Author : Willard Thor Rafnsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; information security; privacy; static analysis; information flow; program analysis; confidentiality; dependency analysis;

   Abstract : This thesis improves the current state of the art on information-flow control of interactive and object-oriented programs, respectively. Given a policy which specifies which information flows are permitted in a program, the objective here is to ensure that only flows satisfying the policy can occur. READ MORE

7. 20. Robust Real-Time Estimation of Region Displacements in Video Sequences

   Author : Johan Skoglund; Michael Felsberg; Hanno Scharr; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; tracking; subpixel; real time; covariance; pose estimation; Image analysis; Bildanalys;

   Abstract : The possibility to use real-time computer vision in video sequences gives many opportunities for a system to interact with the environment. Possible ways for interaction are e.g. augmented reality like in the MATRIS project where the purpose is to add new objects into the video sequence, or surveillance where the purpose is to find abnormal events.
