6. Models and Algorithms - with applications to vehicle tracking and frequency estimation
Sammanfattning : This thesis considers two different research problems; one concerned with the issue of tracking vehicles and one related to estimating frequencies in harmonic signals. The vehicle-tracking problem is addressed from the perspective of an automotive-safety application, which seeks to monitor the course of surrounding road users with the objective to make decisions regarding if, how and when to intervene.

7. Motion Perception and Tire Models for Winter Conditions in Driving Simulators
Sammanfattning : Many traffic accidents happen due to winter conditions, like slippery roads and limited visibility. The road administrators put a lot of effort into snow removal and deicing the roads. The vehicle manufacturers have been working with functionality to support drivers in winter conditions (studded tires, ABS, ESC, etc.) for decades. LÄS MER
8. Motion Vision Processing in Fly Lobula Plate Tangential Cells
Sammanfattning : Flies are highly visually guided animals. In this thesis, I have used hoverflies as a model for studying motion vision. Flies process motion vision in three visual ganglia: the lamina, the medulla, and the lobula complex. In the posterior part of lobula complex, there are around 60 lobula plate tangential cells (LPTCs). LÄS MER
9. Tracking and radar sensor modelling for automotive safety systems
Sammanfattning : This thesis studies the problem of tracking in the setting of an automotive safety system. In particular, it considers the problem of estimating the surrounding traffic situation using observations from radar sensors. LÄS MER
10. Filtering and modelling for automotive safety systems
Sammanfattning : This thesis makes five important contributions to the development of an automotive safety system: filtering algorithms, three modelling frameworks concerning the usage of radar detections in tracking, vehicle motion, and decision-making for intervention decisions, and finally the implementation architecture.In the filtering context, we have developed a new sigma-point method for estimating the moments of a transformed Gaussian random variable.
